If you can, get some more photos of the what the scabs look like now.
Let me ask you something, I'm just asking questions, no accusations. I'm on a hunt here to see if there's a correlation between the scabs and the use of Permethrin. Just speculation on my part, I *think* I have seen similar in other older threads but need to track them down to see if the rabbit hole leads to anything.
Did you spray her with Permethrin or dip her?
What product did you use and if it needed to be diluted, what dilution did you use?
Did the scabs on her backside appear before or after treating with the Permethrin?
Any chance she was treated way back with Permethrin, then the first scabs on her comb/wattles appeared?
If you can give remember the timeline of the first scabs to now and what, if any treatment you administered may be helpful.
Let's see the photos. Soaking may help, it's hard to know. I'm thinking that she may need bathed in a dandruff type shampoo (the scabs) but can't say for sure as of yet. Can you tell if there's pus under the scabs?
Of course Kim (
@Eggcessive ) may have better suggestions than me!
I know it's asking a lot and take your time getting the info. I still need to do some reading/research. I may be on the wrong track all together.
I agree with you on treating like Sour Crop.
