My 25 week old Ameraucana, who has not layed yet, just started sleeping in the nesting box. For the past few months, since they were moved outside and into their coop, she has always slept on the roosting bar but last night and tonight I've found her in the box. In the past week her comb has become a little more visible and red (still small though, of course, because of breed) so I'm hoping she will being laying soon and maybe this odd change has something to do with that. Any idea why her sleeping behavior has recently changed? Is this "normal"?
