This feels like when we first had kids ...everytime one of them would have a fart crossways, we'd call our parents to make sure everything was ok... I've got a 20 week old pullet just starting to lay. This morning while on the nest she starts screaching like a hawk..I went in to check on her, and she's just sitting there calm as can be. Then 5 minutes later another screach!....then another ...for the last 20 minutes or so....she doesn't seem distressed or anything. She is a rather flighty bird, a mutt from a barred rock roo and ancona hen... This is the first time I've heard it.....is it anything to worry about?
