My Eastern hen Ellie always seems to be up on the roost perch every time I go out to the pen...She shares then pen with three laying hens and it's a pretty spacious pen..I know that when one of the hens went broody and had chicks she got beat up for getting too close to the chicks. But She hangs with the chickens just fine when they are out and about in the backyard... Is this normal or should she be on the ground more?
