Hi,
New to chickens and this forum. My wife has really wanted chickens ( Layers) for awhile now so I converted our shed into a coop. We used a couple old pIanter box benches for nesting boxes and I built a ladder roost. I haven't put the chicken door in yet or any fencing outside yet. I found this page because I know nothing about chickens and have been reading like crazy.
I 'm trying to figure out how much ventilation I'll need to add. We have 3 Amberlinks and 3 Buff Brahamas and will maybe add 3 more Ameraucanas for 12 chickens at the most. I was thinking of using these 3 inch round vents I have laying around and putting about 6 in around the top of the walls. Not sure that's enough or not.
Any advice on ventilation or on my coop in general is welcome.
