I was just down in the basement hanging out with the almost 3 week old chicks. (by the way we introduced meal worms tonight...it was a big hit)...anyway...2 of the Buff Orps were constantly at each other. They would sort of square up to one another...then have a stare down, and then each would jump at each other, flaring their wings, pecking and trying to jump on the other...then they would stop...lift their heads as high as possible and repeat. This happened like 4 or 5 times in the span of a few minutes. Is this usual behaviour for hens...or am I looking at one or maybe even two roosters? thanks for your thoughts.
