I have 13 babies about 8 weeks. No true clue on which are pullets or roos. Except for the infamous "Noodles"( If Y'all remember the little chick in the bowl.) Well he/she is now getting aggressive to a few others when feeding and today Noodles fluffed up the neck feathers and wings at another chick. Do pullets do this? Could my "sweet noodles" be a roo?
