If I am not mistaken you free range your birds 24/7 on a piece of land much larger than the biggest of chicken coops, not to mention all the brush and foliage a bird can hide under. Free ranged and caged birds behave differently, especially when it comes to hierarchical disputes. Let's not forget the breed in question is seramas, not any other bantam. Just a quick look around BYC and 9/10 serama keepers will tell you it is not a good idea to mix serama with LF birds, much less a hilariously tall gamefowl
