Hi, I have a chinese goose that's about a month old, and I've noticed that she sits and stays seated a LOT. She doesn't seem to like to get up at all. I'm worried that she might have weak legs, as I've heard that it's a common problem among geese. Is there anything I can/should do or watch out for? Right now, the goose is on chicken feed and left outside in a grass field where she gets plenty of greens.
