I have some baby chicks that have already got most of their feathers in and they haven't startes roosting yet. I've actually seen one or two on it but at night when they all lay down to go to sleep they still form a little nest of chicks. My other set never had a problem and took to it by this time. I don't know if they're are just late bloomers or if it's something else. I figured that they will take to it on their time and when they want to but then i thought well maybe i'd just better check to make sure. Thanks a lot. If i'm right great if not any info would be appreciated.
