I have 3 chicks that are 6 weeks old. They moved into their coop last week and everything has been great! I read that I should block off the nesting box at this phase so they they don't learn to hang out in there. My solution was to stuff it with sheets we don't use. Tonight I checked on them after dark and was surprised not to see any of them in there! After looking closer I saw a tail poking out from under the sheets. They all crawled under there to sleep! They have 2 roosts that they aren't using...should I be concerned or appreciate the cuteness?
