I have a chick named Clover,she's going on 4 weeks this week. All my gals are still in their brooder in my bedroom,and Clover has always been a bit different. She's a Buff Orpington,so the breed itself shouldn't be a problem from what I know. She's always been skittish,she runs like a roadrunner if I reach in to get her or one of the others;but she's fine once you hold her. Now she's doing something I've never seen any chicken do before! If I go look at my girls in their box she looks up at me and she holds her beak open. It looks to me like she's trying to be a snarling dog or something. It's only been the past few days that she's done this,but I've never seen it before! Is this normal!? Please Help Me!
