For the last week or so, two of our 6 month old hens are squating and holding their wings out when we pet them on their backs. It took me awhile to figure out what in the world they were doing. I thought they were in attack mode! Then when they started wiggling their butts, I figured it out EWW I keep asking them, "Do I look like a rooster???" Do they start laying soon after they begin doing this? Oh and one of the two that have been doing this has been walking around letting out this horrific sound, it's kind of a yell like "Ra Raaaaa, Ra Raaaaaaa" Could this be related or is this dominace.
