My silkie Jethro is broody. Yeah, like that's news. Jethro has been coming off her nest for about an hour once a day; perfectly okay with our triple digit temps. For some reason when Jethro comes out she seeks out one of my older dark brahma hens and attacks her. The same hen every time. The brahma is not bothering Jethro or her nest, but Jethro has a vendetta with this hen. I'll admit it is kinda funny to watch a 9 lb. hen try to run away from a 2 lb. silkie. Does Jethro have a valid reason or is she simply being another weird silkie?
