About a month ago, I moved a 4 month old rooster and pullet into a coop that had 5 5 month old pullets. They free ranged a few hours every day before I made the move. All seem do be doing well together. This weekend I watched my Andalusian pullet challege the rooster. Then, a bit later, the rooster attacked her/him, hurt her/him pretty good, lots of blood. I never suspected the Andalusian was a rooster, but I have been fooled before. She/he is not laying yet, the others are, but not for very long. My question is, would a rooster ever do that to a hen or pullet? Is she/he definitely a rooster.
