(edit) Sorry if I put this in the wrong place. I plan to buy 6 more rare birds in early spring, then breed them together eventually. I already have a large coop built for my five RIR and BR chickens. They are kept in covered pens, which are moved everyday to get them fresh grass. I wanted to do the same thing with my other chickens, with three pens total. Now, my question is, if I did that in the day but locked them in the same coop at dusk, would they still crossbreed each other and would the roosters fight? I let them into their pens at 6 am every morning.
