I've got the brooder all set up and am really excited about adding babies to our flock! I am planning to pick up a 3 day old Ameraucana and a 3 WEEK old light Sussex. Is there any potential problem with raising these 2 birds together in the brooder? Will the older one pick on the baby? I just want to know if it would be better to pass on the 3 week old and stick with babies of the same age. This would mean sacrificing my fist choice breed (light Sussex) in exhange for a light brahma, I'd love advice, thanks!
