I have a 4 yr old Chinese gander that recently lost his mate. What is the best way to replace the goose? They were raised with 6 hens and a roo was recently introduced. They free range during the day and share the same predator-proof pen at night. There is a chicken house and a goose house, but the roo dominates both and all the feed dishes...besides chasing the gander around. I'll have to find a mature goose, right? And will she likely be accepted by the gander? The pen is about 35' X 40'. Will the "dynamics" be too much for the same enclosure? I would appreciate any and all advice. These were my first geese. David is very sad and lonely.
