8-9 week old chicks loosing feathers

[Chic Rustler]

Guys i need a little help here. I just found that 3 of my seven chicks that share a space are loosing feathers. I dont know if they are fighting, have mites or some disease. I have the 3 quarantined right now but i am afraid they need to be culled asap. Pics to follow. Thanks for the help

That just really looks like chicks growing their new feathers

They were feathered out a couple weeks ago when i moved them outside. Im not sure. Still pretty new to this. I didnt take any chances. I removed the 3 with issues, and dusted them all with sulfur, coop too.

Chicks get most of their feathers at 6 weeks, then at 8 weeks they molt them out, and grown in their new ones

Those are new feathers just growing in. Not a problem, but that looks more like a 4 week old, not an 8 week old.

My 5 week old chicks are now where that big, and feathered. I'm fairly certain that they are indeed 8 weeks old.

I rechecked my hatch date for these. 3/2/17 sorry i got so many going its hard to keep up. So they are about 5 1/2 weeks or so. Still i swear they were feathered when i moved them outside a couple weeks ago
