OK,so I have posted in here a few times about my newly adopted / rescued hens. I had found a super tiny yolkless egg and was told it was called a fart or wind egg. Well, I have found 2 more since then. I don't know if it's the same hen or not, they all lay the same color except for the EE and production red (who is currently separated for feather plucking). Nothing about our routine has changed, so I'm wondering why I keep getting the fart eggs and what I can do to prevent them. Also, I felt the need to check in on the ladies tonight and none of them were on the roosts. They were all sleeping under the roosts on the floor, all spread out,not huddled together, which really surprised me. The lowest roost is only 12 inches off the ground and they are set 12 inches apart like steps, so I know they could get up there if they wanted too. Are they sleeping in the deep litter on the floor because they're naked bodies are cold? Or is it possible that maybe they never even had a roost at their previous home so they don't know what they're for? Isn't it instinct to sleep off the ground on roosts? So I checked in on the production red, and she is sleeping on the floor of her coop too. It's so weird. Also, I was planning on placing an order for chicks in Feburary at the feed store. With this floor sleeping behavior rub off on the pullets when I add them to the flock?
