I was in my coop cleaning cages. I heard a hen screech loudly in the pasture. I looked up and saw my game hen who has month old chicks meet a large Cooper's Hawk (an adult female) head on. I was sure it had a chick in its talons. She beat the hawk off and even flew up in the air after it when the hawk took off. I counted the chicks and all were there. The game hen is not that large-- the hawk looked larger. She is a Brown/ Red and is molting so even looks smaller than usual as she has no tail right now. I would not known it happened had I not been outside at that moment. I have always said that my game hens never lose chicks and I let them free range. Some of this is luck I know but a lot of it is that game hens are aggressive mother hens.
