watch when your rooster crows the females around him they mite i am not sure they do it if a rooster has been with them like u noe covering them but yea kk this will sound weird but i am like the rooster of my flock in every sense of the word
i crowed once and heheheh and they did it so i played a recording of a rooster from utube and they didnt respond so they are weird
