My 18 month old hen attacked me out of the blue. I just have 2 chickens, raised from chicks, there like my pets, free range in backyard, wander in the house sometimes. So she is very used to me. I was just filling the water bowl for them, they were watching me and she attacked my leg and drew blood. Can't figure out why, wasn't near the hen house or their eggs etc. Anyone experience this from a hen? Thanks.
