I am new on having/taking care of chickens. I have 10 chicks from hatchery, ordered female. I know there can be still cockerel in between them since even they are not %100 correct. Their birthday is October 7th. So by now, they are 10 weeks old. I still have no clue on their gender. So, these are the same age. And am I right to suspect, the one in front is cockerel? Anyone has experience/knowledge that might help?
