I have some questions. I'm planning on pasturing 48 layers. I'm going to be using electric netting to keep them contained and I can give them plenty of pasture. That's not an issue. They can have a 1/4 acre of new pasture daily on a 120 day rotation. That's my maximum capacity for pasture. They'll be following my cattle and sheep. I am building an 8' x 12' "egg mobile". Half of the egg mobile will be filled with roosting the space. The other end will have a dozen nest boxes made from 5 gallon buckets on a frame. The birds will only sleep in here and lay in here. During the day they will have free run of up to a quarter of an acre. Has anyone ever used truck bed liner to "paint" their laying houses? I think that it would be an ideal way to seal everything and make them easy to clean and disinfect. Also, Will seven 6' long 2x3s be enough roosting space for 48 hens? Technically there will be an 8' long 2x6 on its edge that could be used as well. I just want to make sure that everyone can get up and get someplace comfy to sleep. Will a wire floor under the roosting area be enough ventilation or should I install removable cross ventilation panels as well. Georgia gets some hot and humid summers. Thank you for the advice.
