I house my 8 chickens and 2 geese together. First I got the chicks, little bitty, then about a week later I got the 3 day old goslings. THey all did great together albeit one of the geese pulled the tail feathers from one chicken - and yet another chicken thinks it is a goose. But when they come out of the coop during the day, usually it's the chicken w/ 2 geese together and the rest of the chickens are off together. Somehow, there are never 8 chickens together... Anyway, the geese are now about full grown, I think, at 5 weeks?? and I have no idea how much bigger the chickens will get, but no body has been bullied yet (that I know of). THe chicken who's tail feathers were removed, never minded, I think she thought she was being preened! jennifer
