So I went out to spend some quality time with the girls (about three and a half months old now) for the first time in a few days due to rain. I noticed what looking like a little bit of blood on their ramp up into the coop but they both seemed to look and act normal. After a bit longer, Patsy (the silver one) gave Eddy (golden) a hefty peck on the butt. A few minutes later it happened again and Patsy had blood on her beak. It looked like Eddy had some blood on her tail feathers. Is this just them sorting out the pecking order? (I had thought Eddy was top bird before this but Patsy has grown bigger) Do I need to separate them for a time? How concerned should I be?
