I REALLY want 3 more chicks..... There is an add on crigslist for some EE chicks..... HELP! I already have one adult hen and I just love her. I do have 3 black sex links that are like 3 weeks old, born in the back yard. I was wondering if i get these babbies if i can add them to the 3 3 week olds? The add said the EE chicks are 3 weeks old. Would they fight? or would it be ok?
