From what I'm reading, Shamos are best kept in breeding pairs, and may not do well with other chicken breeds due to aggressiveness. Is this what people are finding? What size coop and pen does a pair need to be content? Is it okay for the roosters to be in eyeshot/earshot of a roo of another breed, assuming they can't reach the other, or will that stress them out? Has anyone ever had theirs threatened by hawks? They seem big enough that a hawk would leave them alone. Are they intelligent birds? I'm wondering about the possibility of letting some out to free-range with supervision and teaching them a recall command to bring them in. That shouldn't be too difficult, right? Anyone ever tried to teach them or another game species to walk on a leash?
