I have three peahens I raised from chicks. They are about 5 months old, I raised them with 12 polish lace chicks and have kept them penned together until last month. The Polish Lace can't fly out of the pen and I wanted the peas to free range so when they had to be moved to a bigger pen I left the screening off their new home. All has been well for about 4 weeks, all three peahens hung out together, you never saw one with out the other two bringing up the rear. Well it got cold last night around the mid 30's, the first time this winter. This morning I was missing a peahen, I looked around the yard and on top of their favorite roosts, no peahen, no feathers and no body. Should I assume she just flew away? She definitely left overnight, I just wonder where she went?
