I have a red and white hen who is just over 12 months old. She is losing feathers and looks quite forlorn. Her tail feathers are quite sad with the "fluff" broken off the shaft. She has lost sufficient feathers to be bare over her crop.
The other 7 hens are all fine - I have seen fallen feathers of all colours of recent weeks and think they are all moulting but this particular bird seems to have taken it to extremes. She isn't either the top or the bottom of the pecking order, but I haven't seen anyone be particularly aggressive towards here.
Should I worry - or will Rosebud once again come back into full bloom?
