We ordered 10 chicks total, received 18...they added some roos for warmth. All the chicks are doing well, except for 1 crevecoeur the runt of the litter...it was very lethargic, off balance and stayed away from the group. it woulnt eat or drink so my GF decided to try and load a syringe withs some cooked oatmeal and feed it that way...it worked, the chick is doing much better now, and chirping louder than the rest of them. How can I tell which bired I have are the roos? I cant keep those So I'd like to know just how many are in the bunch. I saw something about the wingtips are different on male and females.
