We have have 2 yr old sex links and barred rock hens that have been together since baby chicks. Just started to notice them not getting along so well. Sex links to have more of an attitude than the barred rocks. Do some breeds go through a chnge in behavior as they get older. Our older flock of 5 yrs is mixed with 4 different breeds with no problems as mentioned before.
