The chicks are now 16 days old, and have grown so much! It was too cold to get them out of the brooder and weigh them, but we’ll do that soon, on a nicer day. I did need to raise up one of the heaters because the larger chicks had to duck and crawl to get in. I kept the other one down low because we still have smaller chicks. Their colors are definitely changing and differing. We have lighter shaded chicks and darker chicks. The feed store said that their chick source guaranteed 95% females. This should be interesting.
