Brahma Chicks feathering issues

[omgdoubletacos]

Hi everyone, I have 3 partridge Brahma Chicks that are about 11 weeks old. They all have hardly any feathers on their backs and vent areas. The pullet isn't as bad off as the cockerels. This had been an issue since they were first getting their adult feathers. This is my first time raising brahmas from chicks; I know they're slower to feather, but this seems abnormal.

All 3 are eating well and drinking. They free range with the rest of the flock during the day and get locked up in the coop at night. I haven't seen anyone picking on them and haven't seen any parasites (mites/lice) and they are the only 3 affected. What are your thoughts? Should I separate them to see if the feathers start to come in or does this seem medical?

I've included pictures of the boys. Please let me know if more pictures are needed Thanks!

Apply Nu-Stock to the affected area. It will heal and prevent any feather picking when you're not watching your birds. You can buy it at a feed store in the equine section. Shake the tube well and wear disposable gloves when applying it.

How often should it be applied?

Once you apply the Nu-Stock, it stays on for awhile, no need to apply on a daily basis. Then apply only as needed.
