We've just got our Go Up (thank you Gumtree gods) and will be having a look at chickens this weekend. The manual says 2 large, 3 medium or 6 bantams. I'd like 3 different breeds and am wondering if, for example, 2 medium and 1 large hen would be ok. Anyone with a Go have any thoughts on this? I'll give the chickens the run of the lawn as much as possible if that's any help.
