they Are more for my mother in law. She has a couple EE's and wants a chick a little older to go with this other chick I'm getting for her. I wish I could have a rooster here. They are prettyWould any younger work? i have and EE female and male chick that are 6 weeks old and already outside and off heat and doing great. They are big chicks, they came from McMurray and must have come from big eggs they were nice and plump and have grown crazy fast. They are bigger than some that are much older than them. I can post a pic if you are interested. The female is the golden color and the male is the Columbian type color with the white and chocolate.
