I have 4 chickens. Two are practically inseparable. One is a BCM and the other an EE. They sleep together, bathe together and generally just hang out. They get along really well as do all four of them. But the BCM likes to "groom" the EE. It's usually if she has food or sand in her beard. So the EE has no feathers under her beak. I wouldn't call it the normal pecking. I've seen her do it and it does look like grooming behavior. There are no other feathers pulled. I've tried BluKote. Looks great on my white EE. But it doesn't seem to stop the BCM from pecking. When I put the BluKote on the EE she just hold her neck up and lets me apply it, very much like she does when the other is pecking/grooming or whatever. No broken skin, no blood. And there's no squaking or "fighting". They all get along and I don't have a problem with any of them. Any ideas????
