I have a 4 week old White Crested Black Polish with a cross beak. She is the sweetest little thing and will always come to my hand when I put it in the brooder. We give her wet food mixed with Gerber baby food and we give her water with a dropper a few times per day. She acts pretty normal and is always happy, but, she is about half the size of the other chicks who are just a week older than her. She already has her feathers but she doesn't seem to be growing as fast as the other chicks (A Lavender Orpington, a Calico Princess and an Ameraucana.) Do you think that she is just a slow grower or is it because she's not getting enough of something? Also, is there anything that might help with her cross beak?
