She discovered them when she went broody and was trying to get back into the coop through the windows because I locked her out of the coop while I was in there installing another poop board and roost.
I did silk flowers in large pots on the ground and they had a field day with them. I still find an occasional silk flower as I pass through the pen and I removed the pots last fall.
I'm still going to try fake flowers in the window baskets for autumn. It isn't easy for her to stay in those baskets because the frame is metal and narrow. I'm hoping when she samples the fake flowers a few times she'll give up.
