Hi, new Chicken owner. I have Lavender Orpington Roo hatched approx April 15, picking on EE Hen hatched April 1st, 6 other Hens in flock, just picking on her. They’ve been together since end of April & this just started. I’ve separated her, tried to reintroduce her, & he starts again within minutes. She hides from him...is this normal because he’s a young Roo or should I be worried? I hate keeping her isolated.
