My second order of chicks (Barred Rocks) are 3 1/2 weeks old. Today when I went to the brooder to change the water and fill up the feed, I noticed that at least 6 of my "girls" are developing a red comb!! I am going to wait until the end of the week and separate them out to count them but I did not get 'extras' with my order. Is there a nice way to go about getting the hatchery to credit me (as I paid the Pullet Only prices). Also, I did not know what I will do with them, or how early I should be separating them. I do not want fertilized eggs. They are feisty little buggers.
