I was given 6 baby chicks a week ago, they are now 2 weeks old. I have 4 black, black with white. 2 are pure yellow or maybe white ? I would say yellow but every day they llok more white. One is growing a ridge along the top of its beak. Some have dark legs some don't The person who gave them to me doesn't know what they are. They were given the eggs. Large brown eggs. Thanks!
