For nestboxes I buy the largest covered kitty pans I can find. They work fine for my brahmas, so I'm using them in my baby coop too. I have one, will be buying more this week. In my juvenile's flock temporary home I was finding eggs everywhere but in the nestbox. Couldn't figure it out. Now the juvies have moved to their permanent coop. That coop includes a small wire dog crate that I intended to use as an isolation and/or broody cage. I even put some hay in it on top of the shavings in case my silkies wanted to sleep in there last night. Go to check on the babies this morning and one of the CXs is in the crate, clucking happily and re-arranging the hay all around her into a nice nest. She's been sitting there for two hours now. Apparently even the large kitty litter pans aren't big enough for CXs. Anyone know where I can find the world's largest kitty litter pans for my CXs?
