We got our chickens sexed when we first got them and and now they are a month old. We wanted all laying hens but there's this one..it's name is Boba..I think it might be a rooster. Everything is different about it. personallity, its crazy (hence the name. it means crazy in portagese) the color of it's feathers and the size. Is there anyway I can tell if it is a rooster or a hen or do I have to wait till it grows up?
