I'm just throwing this one in to say baldness does not always mean moulting.
This is Moel
Moel means 'bald'.
This young lady is 4 and that is about as many feathers as she ever has on her head. No Naked Neck genes,either. It isn't caused by the boys,either. She is supposed to be a Blue Partridge Brahma. She took almost a year before she had her adult feathers,being mainly downy up until them. She Has odd looking feathers on her wings and cannot fly (Brahmas rarely try,anyway, as they are too heavy for their wings).
Moel is one of of only two of my hens who are currently laying.....5 or 6 days a week,good strong eggs.
So,although my lawn is inches deep in feathers,they are not hers.
