Ok...So I have another question... I have birds that are free run in pens within my chicken house but I want to change their pens and add them to others... My question is, when I do, they seem to fight for a while so do you let them fight it out or not introduce them? I am trying to pair everyone up but I have a white hen that when I put new hens in with her and the rooster, she chases them in the pen. The pen is 4'X6'X6'. Has wood chips and a brick floor so no wire pens for them. Thank you in advance!
