Hen Losing feathers on top of head?

[14chickmama]

Hello I have a 25 week old BA that Iv e noticed her feathers missing on the top of her head. She seems to be the only one like that. Is it from the roosters? I have 2 Roos. Or molting I dont know how old they start molting. They just started laying about 5 weeks ago.
for some reason they loaded sideways sorry! Thanks!!

Moulting could have something to do with it. Or abuse from roosters.
I would also check for lice and mites. They are common reason for loss of feathers, bare spots.
Fungal, yeast, bacterial infections can do this. Watch for swelling, redness, enlargement of area. I would watch her overall health. Watch your other birds. Consider isolating her especially if it worsens.
