Thanks Miss Lydia. The outside pens are pretty big, and they get turned out into the yard every day when I am home to watch them. I try to make sure there are nesting boxes, clumps of weeds, big water tubs, etc for them to be able to get away from one another and to provide interesting stuff for them to do rather than pick on each other. When I put birds together, I am always watchful for several days to make sure they get along OK, it's just this is my first foray into geese. Wasn't sure if they would acclimatize like my chickens and ducks always have, or if there were any special considerations with geese.
