I am interested in either miniature geese or Sebastopol Geese. I only have 3/4 of an acre. I don't want to breed so I was thinking 2 males or 2 females. If I get them young can I raise them with chicks?
If you're planning on keeping them with chickens, go with the females. A gander could really hurt or even kill a chicken trying to mate with it. You can raise them with chickens - my goose Lacie was raised with chickens - but they will quickly outgrow the chicks and there is the danger that they might step on them and hurt them. I recently raised a roman tufted with Calls and he was very careful of them and did not hurt them, but it's something to be aware of.
Another thing that happens is that chicks mature much more quickly than goslings do, so even though your goslings will be bigger, the growing chicks might actually start to bully them.
A divided brooder, so that they can see and interact with each other but can't actually get to each other, might be a good plan. That way they still grow up together but no one gets hurt.
