I have a 16 week old RIR cockrel. His very sweet with people, you can pick him up and hold him all day. I also have 4 pullets, 2 fullblood RIR and 2 white red cross RIR girls. The 2 white-red girls are mostly white but have some red. The problem is, my cockrel loves the two red girls but he HATES my white girls. He wont even let em stay all 4 girls together, he keeps the whites ran off. If they even come close, he runs up to em, neck feathers out all pist off. Is this normal? or signs of a bad roo?
