I have one chicken that has been missing for about three hours now. Speedy and Fancy (The rooster) have not been getting along the past three days or so. We have also noticed that we can't figure out where she's been laying her eggs the past few weeks, if she's laying at all. She seems to be healthy except for some reason she's growing new feather's on her head and neck (she is the only one). I'm hoping she could be brooding and not been carried off.
