Breezes and Drafts – Proper Ventilation Keeps Chickens Comfortable and Healthy

The only difference between a breeze and a draft is temperature.

Both people and chickens savor a cool breeze on a sultry summer evening but that pleasant summer air transforms into a knifelike January draft that slices through the coop and chills hens.

It can frostbite tender combs, freeze water containers quickly and make life miserable for the coop’s occupants.

Proper ventilation is critically important to keep chickens comfortable, safe, and productive. Well-made coops enable managing airflow to welcome summer breezes yet bar frigid drafts.

Managing a coop’s air starts with litter and manure. Almost as soon as litter gets wet odor permeates the coop.

Soggy litter, caused by leaky roofs or tipped over water buckets, generates ammonia that no amount of ventilation can transport outdoors.   Well managed coops don’t smell.

The secret in preventing odor is to make sure no rain can enter and that any damp litter is immediately removed and added to the compost bin. It also helps to keep chicken density low. Crowded coops are more likely to be pungent than those where chickens have plenty of individual space.

Managing Coop Airflow

A well-designed coop has at least two windows on opposite sides for cross ventilation.  Ideally the chickens’ roost is located between them so the birds enjoy summer breezes while snoozing.

Windows should be easy to open and close so the volume of air that passes through them can be adjusted depending on the temperature.

During summer’s inferno, they should be wide open but cramped shut in winter.

Spring and fall bring mild temperatures and windows only need to be open an inch or two to let enough fresh air in.

Windows do more than admit air and light. They can be the entryway for raccoons, opossums, and even mink dreaming of a tasty chicken dinner. Windows should be configured to exclude predators while welcoming fresh air and light.

Good coop windows have three layers. The first is the glass that permits or excludes breezes depending on how far they are opened. The second is mosquito netting to keep biting bugs outside.

Insect screening is not strong enough to even slow a hungry raccoon, so the third layer is a mesh of wire strong enough to deter powerful predators.   A heavy-duty mesh screen can be made of 2X2 lumber with wire stapled onto it.

The frame is then screwed over the window. One half inch square hardware cloth will even keep out lithe mink.

Glass plus netting plus wire screen let in a summer breeze while frustrating hungry bugs and furry predators.

Breezes and drafts don’t just enter at windows. They discover every crack and hole in the coop and enter uninvited.

Even in the coldest weather fresh air entering through a few cracks brings the oxygen chickens need and voids moisture coming from their breath and manure.

A few narrow cracks are good but too many let frigid air in and can be an entryway for weasels.

Filling most cracks with caulking or expanding foam every fall helps keep both the cold and skinny predators outside.

Chickens have a high heat generating metabolism and feathers, nature’s best insulation, to keep the warm. In an uninsulated but draft free coop body heat raises the interior temperature a few degrees on the coldest nights.

When nature’s mid-summer furnace is going full bore roosting chickens pant to increase cooling evaporation from their throats, and they often hold their wings outward to void body heat.

Having plenty of roost space allows them to partly spread their wings. That and a cooling breeze helps hens enjoy a good night’s sleep. On the hottest and stillest nights hens may appreciate an artificial breeze from an electric fan.

Managing coop ventilation keeps chickens comfortable, clean and productive and is an important task of any flock owner.

How to introduce new birds to your existing flock

 

Birds of a feather truly do stick together. That’s why it can be a challenging task to bring new birds into your established flock – new flock members often get picked on and harassed by hens who don’t want to share their territory. For a seamless integration of new birds into your flock, there are a couple of tricks that work well. All you need is patience – and some ninja-like moves.

To start with you want to make sure that your coop/run setup is large enough to accommodate the new birds that you are adding. Each adult bird will need 3-4 square feet of space. If bringing in birds from another flock, make sure they have been through a quarantine period of at least 30 days and are healthy.

Keeping new birds in a cage will let them interact with the flock without being harmed.

You’ll want to introduce birds to each other gradually and let them interact without the opportunity of pecking or abuse. To do this, place your new birds inside the run or coop in an area where they can see and get to know each other but where they are still separated. A wire cage works well, but you can also put new birds into a dog crate or use chicken wire to fence off a portion of the area and make two separate spaces. If introducing new chicks to your flock, you’ll want to make sure they are fully feathered and acclimated to the coop temperature.  You want to keep new birds in their own area and let everyone get to know each other for at least two weeks. Patience is key here, so don’t rush the “getting to know you” phase.

The ninja moves come into play when it is time to introduce the new birds into the existing flock. Wait until night, when it’s dark and all birds are sleeping comfortably. Moving quickly and quietly, you want to take the new birds from their resting spot and put them on the roosts next to your other sleeping birds. When the birds wake up in the morning they are next to another hen that they are familiar with (because they’ve been in close proximity, although separate areas, for several weeks) and they are often tricked into thinking that they’ve always been together. You’ll want to carefully monitor the everyone during the next week while the pecking order is reorganized, but this approach should give you a fairly seamless merging of your flock.

The right nutrition at the right time for layers

Timing is everything when it comes to feeding your laying hens. Ensuring they have the correct nutrition at just the right time is an important part of having a happy and healthy flock.

Hatch to approximately week 6: Provide free choice access to a quality chick starter ration and make fresh clean water available at all times. Proper nutrition in this critical growth stage will impact the performance of the chicken for their entire lifespan. Use a heat lamp to keep birds warm and provide 1 sq. foot per chick.

Approximately 6 weeks to 16 weeks: Continue to provide free choice access to chick starter and water. If you choose to feed treats (scratch grains, kitchen scraps, etc.), put out what birds will consume in about 15 minutes once per day. This a good guide to follow to make sure treats don’t exceed 15% of the total diet. Add treats only after week 6. If birds have access to anything other than a crumble or pellet, provide grit free choice in a seperate feeder.

16 weeks +: Now is the time to switch to layer feed! Provide layer pellets or layer crumbles and grit free choice along with access to fresh clean water at all times. Treats can be provided at no more than 15% of the diet. At this point it is also important to make oyster shell available free choice to provide supplemental calcium for hard-shelled eggs. Adult birds require approximately 3-4 sq. feet of space per bird in the coop; you also need to plan on one nesting box for every 4-5 hens.
