Hi there, Petrie, my BR hen, seems to have food agression. She's a really good hen... until I give them treats. Then, she'll turn to whoever else is eating and grab their comb and start pulling and shaking her head... like a dog in tug-of-war. She'll do this at the feeder, feeding them out of my hand, or when I scatter scratch. The other hens let out a really loud screech when she does it... and it's really sad. Pinless Peepers are probably not an option (unless there are no other options.) Thanks.
