My bearded hen has lost her beard.
She's a 2-year-old bearded Polish hen. She moulted last fall, after which the feathers grew back as expected. Then this spring she lost just her beard. Her other feathers are staying put. I keep expecting her beard to grow back in, but it hasn't. I don't even see any feather sprouts.
No one pecks at her; in fact she is the boss chicken. She seems perfectly healthy other than her missing beard feathers.
I have one other bearded Polish and her beard is fine (although she started another moult a couple of weeks ago.)
Does anyone have any suggestions as to what this might be the problem, and what I might do about it?
