Last week, I lost one of my two chickens to a dog. I immediately went out and was given a hen from a friend of a friend. I didn't want Betty White to be lonely. Well, I don't know what kind of chicken Reba is, but scared and terrified are the first words that come to mind. I have tried the girls in the coop at night and seperation in the day... well, it isn't working. Betty went after Reba this morning, that I am not sure .... I have washed the wounds and seperated them. The only place Betty attacks her is at the top of her neck, like she is going after her brain. She was bleeding terribly. I have two baby chicks with two more to come shortly. Do I need to have two coops and keep Reba with the babies when they get old enough? What to do, what to do?
