The mother hen is bossing the other hens and even the rooster gives her space. The mom and hens get priority from the other hens when I give them treats like apples, or romaine lettuce heads. I have several feeding areas, but am wondering if I need to create a larger run. I live in an area where there are bobcats, coyotes, and predator birds, so I can't safely let them free range. I have a total of 10 chickens including the chicks. The current run is 8'w X 30'L X 10'H with an attached 8X8 coop. The mom and 3 chicks are always together and I am almost certain the mom takes them into the coop to eat the other hens eggs. Any suggestions?
