Our buff brahma Winnie, is 6 months and the last month or so she has been biting us. When she's laying or in the coop she bites. If you pick her up and she doesn't want to be held , she bites. Today my 12 year old picked her up and had her at eye level and she bit him just below the eye. She's usually fine with him holding her. She acts dominate over our Black Asian but doesn't bother our Leghorn. I'm confused as I read her breed is very docile and non-aggressive. She eats well, is vocal and is active. Really unsure what the issue is. Attached photos for whatever reason you may want to see her.
