I have six 8 week olds. 3 BR and 3RIR. They have been in the coop for about a week and a half. Right now when I go out to lock them up at night, they are all together hunkering down in one of the nest boxes. I know it is not uncommon for young birds to not use the roost right away, but is it a bad idea to allow them to sleep together in a nest box? I don't want them developing bad habits - but really, how do i stop them? Or should I let them be for now? Any input appreciated. Thanks!
