I have a two six week old geese and one of them is having an issue. I had them in a smaller pen for a little while when they were smaller in size. I would get them out a couple of times a day and walk them. The one that I am calling a male would walk were we were going and when I would stop to let them eat clover he would sit his butt down. now weeks later he seems to favor sitting a lot and even in a bigger pen where there is room to roam he walk a little bit and then sits down. I was wondering if this is normal? they are on a grass diet with a little bit of feed but just once every other day and just a little bit. Would there be something wrong with the goose itself like with his heart or is it a feeding problem? Thank you for any help.
