Just got some more chicks last week. Im guessing they were about a week or 2 old when i got them..2 blue ameraucanas and a salmon faverolle. The one blue has a way bigger comb than the other blue; the other barely has one; would that be pointg toward it being a boy?. When i got them the guy vent sexed them and said he thought them all to be girls. They dont have their big girl feathers coming in yet so i cant tell by that.
