Earlier in the fall my 9 month old Olive egger disappeared for a few days and I assumed she was toast but after a few days she started showing up every once in a while and has been back since. Now another pullet about 8 months old is m.i.a. the pAst 3 days. I'm in northern Wisconsin and I'm worried she's getting cold at night and stuff assuming she's alive. Would it be weird for a hen that age to go broody this time of year?
