I have two new chicks this morning ... 21 days on the dot. They are SexLinks - one is a yellow pullet and the other is a cock. What now? These are my first chicks. Should I get the rooster and other hen out of the coop for a while so the chicks can get their legs under them? I think I'll put a small waterer inside the henhouse for them. What do I feed them ... chick feed I'm guessing? Anything else?
