Hi there, I couldn't help myself and splurged on some Christmas hatched chicks from a local breeder. (Merry Christmas to me!) I bought 8 in total, 5 bantam cochins and 3 show quality silkies. It's the most I ever spent on chicks and I'm freaking out a bit because 7 out of the 8 are ALL acting like roo's already. All but 1 silkie are chest bumping, going wild, hopping on top of each other. Have I got all roo's? Do girls exibit this kind of behavior too?
