Chicks with mange???

[Chickenlover4ever!]

I recently got 20 pullets to raise and sell, they have good space and a clean cage. 2 of my smallest pullets are 5 weeks old and experiencing bald spots and dry, dandruffy skin. Is this mites or a nutritient deficiency? I’ve raise chickens since forever and I’ve never come across this problem.

You say smallest pullets, is there an age difference? I would suspect feather picking.

Pictures would be helpful. Some birds can have bald spots while feathering out and it's normal.
