Play, quarrel, run away, yes. I have chicks as young as 6 weeks and adults as old as 3. There are three separate coops. The food arrangement is the toughest part to manage. They all seem to want to eat what the others are having. I won't do it much longer, as I want to separate the Brabanters and I'm trying to help one of the Brabs recover from wry neck, but the different groups tend to protect each other and stick together. I have a total of 32 chickens until I process the 3 meaties.
I have two EE cockerels (CCL x Brabanter or Ameraucana) that are very pretty, but are now over 2 months old and ready to be listed for sale. I should get on that...
