And the "picking" is not an aggression thing. They see stuff like new feathers coming in and nibble at them. But they just keep on til they cause sores and bleeding. We have managed to catch these events early so they are no worse for the wear. And their ages are very close. The 6 older ones, 2 females, 4 males are only 3 or 4 weeks older than the 2 younger males. And they are old enough now you can hardly tell them apart. The 2 younger ones are just a little fuzzy around their rumps. We have put bands on their legs so we will be able to identify them when they finish feathering out and look just like the other 4.
We had a cpg goose kill a smaller cpg gander because he got food all over him and she was picking at the food on his down. (we were not home and caught the behavior too late to save the little guy). She was not mean and did very well with him despite being a good bit older and bigger. She just picked at the food non. stop until she did irreversable damage while we were at work.
You say goose and gander, but you´re talking about goslings, aren´t you?
I think some of his behavior is meanness. He was yanking butt fluff out of the others when they were younger. lol
So are you talking about youngsters, or adults? If you´re talking about youngsters, then he does seem mean, yes.
We got them at the end of June. The younger ones were about 2 or 3 weeks old, the others about 3 or 4 weeks older.
