I've got 5 hens, all about 3 years old and all have been together since they were tiny. They all get along well, but I have one EE who's almost always by herself. They free range during the day and the flock will all wander around together for the most part, but she seems to be by herself more often than not. The other 4 are currently in the back of the house scratching around and she's laying in the front yard dust bathing. She doesn't seem sick at all, she eats, drinks, and will follow the others and scratch around with them for a while, but if they get to a spot she likes, she'll stay there after they move on. Is it normal for a hen to just be a bit more independent than the others?
