My lavender Orpington has been making her 'egg laying' song multiple times a day. Randomly she just starts doing it.. The other day I literally thought she was crowing.. But she lays eggs so she's obviously a girl. This has been happening maybe two weeks. Is this normal? She does this after laying her actual egg, in the middle of the afternoon and she seems to do it just before dark.. She's also my top hen. Back-story.. Her flock mate just hatched chicks about a week and a half ago also.. But wasn't being a good mom so I moved them into a brooder inside. Is it possible she's calling to them, is that weird? She never physically saw the babies but I'm sure heard them. Trying to figure out if I should be concerned here!
