I have two questions..1. Why do some of my girls eggs, occassionally, have a blood spot when I crack them?And are they safe to eat?2. And most of my girls have 'No Feathers" on their butts!They look like red-bottomed baboons..... No kidding! And, I bought all hens. Can one be so dominate that she rides the others like a rooster?? I recently acquired a banty rooster, Hamlet, but he just got here, and I KNOW, he's not the culprit... IDEAS?? Anyway, THANKS FAMILY!!Looking forward to your answers.
