My 3 week old silkies and cochins do something really weird that none of my other biddies have ever done. I have one chick that always starts this, and he/she will start chirping, really loudly, and then all of them will join in. It is so loud, it hurts my ears. When I look in the box, they're all standing in a group, not huddled up, all looking one way, and taking time about chirping. They don't sound scared, just loud. I don't know how long this would last, as I usually get them to stop. Maybe some of you who have silkies or cochins know what they're doing. It seems like some kind of pack "ritual." Maybe they think they're wolves...LOL
