Easter Egger Bald Patch!?

[Marianne56]

Help!
My poor Go-Go Noodlehead (Easter Egger), she's been looking this way for awhile. Now her sister Helen (also an Easter Egger), is starting to show similar feather loss. I thought it might be from one of the lead ladies bullying them, but I'm not sure.. There is a hen lower than Helen, and that is Miss Plum. However she doesn't show these same symptoms. So maybe not bullying.
Does this look familiar to anyone? Is there anything I can do? Thank you

Mine looks the same both easter eggers one on the back like your and the other one around her head/neck. I spray them with the purple spray so the others will not peck her but nothing I have tried has resolved it and no mites.
