I have had chickens for years but this is my first batch of ducklings. I have 9 bantam ducklings and one (Oblio) has started picking on the others, mostly pulling at the wings and tails. They are just starting to get wing feathers so I guess there are "blood feathers" there and when pecked, they bleed profusely. Then of course everyone starts pecking at them. But it is usually started by Oblio. I have been isolating him, by keeping him with the others but with a wire fence between them so he can't hurt the others. Then I feel sorry for him because he cries, so I put him back with the others. Within seconds he pecking the others again...so back he goes. He seems to be the only one doing this. Will this behavior stop? Is there anything else i can do? I am trying to provide them with lots of fun outdoor time, a kiddie pool, etc so they are not locked up in a tight space all day long or anything. Any advice would be welcome!! Thank you.
