Hello everyone, I have three chickens in my flock, two of which are hens (Peanut and Plumps). My rooster (Yin) did not like the hen ever since we got her, but will accept the other hen he was raised with (Plumps). He will chase her around, nip at her, bite her crest, and sometimes he will maim her crest. She is in a separate pen right next to Yin's, and has been there for over half a year, and the condition is not improving. How can I stop this so he will accept the hen?
