I'd be concerned about your lack of space and continued hatching. Sounds like you need to tone things back some until you get your flock healthy again, including enough space. I sympathize as I've also been bit by the hatching but, but my incubator is empty at the moment as I'm out of safe, healthy space for the birds.Thanks a lot for your help... i usually gives them a mixture of different food.. i give them rice with layer feed along with cracked corn chick feed as they have protein this sounds like the birds aren't getting enough protein. Rice and corn are lower protein foods and lower the overall percentage of protein. Go to strictly layer feed, or better yet higher protein chick feed for a month or so.
