My almost 4 and 6 wk. chicks have been in the coop for over a week now. They are sleeping on the floor and I'm having a terrible time keeping the coop clean. There are 12 chicks and I'm ankle deep in poop. I've tried picking up the poop, (but end up catching 1/2 the shavings with it,) then spread more shavings over it with DE. I had to remove it all after only 1 week. I have roosts with a poop board underneath. The board has a lip on it and it's filled with sweet PDZ ( idea I got from another thread). The problem is they won't use it to sleep. The idea was for them to sleep on the roost and the poop board with the PDZ would catch the poop making it easy to clean. The pine shavings on the floor would stay much cleaner if they'd only use the roosts. Are they just too young to roost or have they gotten too used to sleeping on the floor? Any suggestions on how I can get them to sleep where they are supposed to?
