A month ago I lost 3 hens from a dog attack and was left with one lone RIR hen about 1½ years old. I ended up buying 2 one-year-old hens (Black Copper Marans) to keep her company. One of the new Marans hen is so mean to my RIR and the other Marans hen. Everyday when I try to feed them she runs over and pecks the others preventing them from eating. I spread the food out in 3 different areas and anytime one hen would try to eat she’d race over, peck, and push the other hens away. It’s gotten to where during feeding time (2 times a day or more) I have to lock her in a cage and feed her separately until the other hens eat, then I let her out. They are in a large area 40 by 50 ft. and have two houses to sleep in so space is not a problem and I feed them a ton of food plus they have trees, bushes, and grass to forage in. When I get back to school I won’t have time to deal with this nonsense so I’m probably going to sell her. She does lay beautiful copper colored eggs. Does anyone have a solution for this problem or is it a lost cause? When not eating they all seem to get along.
