Hi, I'm a new chicken mommy so I'm learning something new everyday. My four 9-week-olds have been in their coop since the weekend and the first couple nights they were making all kinds of new sounds and scrambling around, which I figured was part of working out a pecking order for their sleeping arrangements. They seemed to have worked it out and last night they were all on the roost together making these cooing noises, which sounded so sweet and contented but I noticed one was making noises with her beak open -- not like chattering where her beak would open and close -- it just stayed open, about halfway. Is that normal? Was she in distress? ...I am worrying about everything as I get to know them more and more!! Thanks for any feedback!
