Hello: I have a hen who hatched some eggs in early July. I have 3 other hens in the flock. We kept two of the hens that broody hatched, they are now pullets (we recently gave the other pullets away.) The mama hen has become VERY aggressive against one of the other hens in the flock. She chases her all day. The hen who she has it out for is not a great layer (though she is on good laying feed and has oyster shell available to her.) It is hard on the hen who is chased all the time because she's not a hearty hen. I know that is also WHY she is being chased. But, it was never a problem until recently as it has gotten really bad. Even when they are free-ranging together! Any ideas how I can break this up? It's really a bummer to have to separate them because then one can't free range. Also, if I don't want to free-range them (it is a small yard and I don't always want them out) I can't leave them all in the coop together!! Thanks!
