I live in the arizona desert and was wondering what i should do for my geese when they are old enough to go outside. We have water restrictions right now so not much fresh grass. our yard isnt completely fenced in so i dont want to free range them, but i dont think i want to put them in with my 7 chickens one of the roosters is slightly aggressive and i just dont think there would be enough room for them all. What should i do?
