Well, Marigold is back outside - in a separate cage - today. I knew it was time, because yesterday, during free time, she would not leave the coop and kept trying to get inside. The minute I got her cage next to the big coop, she started puffing up at Petunia. The two moved like a mirror through the hardware mesh for like 10 minutes. Petunia finally went over and laid down in the sun. Marigold finally backed off a while later. Before, when Petunia attacked her, she just sat cowered down and let her. So, I at least feel better knowing that if they do fight, she is well enough to stand up for herself now. I'm going to keep them together like this, probably for most of the week, and then Friday when my dad can come help me supervise, let them all out for free time together. I think I need to get some of that Blue Kote spray, too, because Marigold's still got a bald butt! Marigold has always been the most aggressive and bossy, so maybe she is ready to reclaim her throne?
I'm betting on Marigold - as long as she has a blue bum!
