Strange flaky bald spot on goats chests

[4HGoatGirl]

I was checking on my goats when Lucy my Nubian jumped up and I saw a flaky bald spot. I put some Fur-Zone on the bald spot. That's when I noticed her sister had it too. I did the same thing for her. Any idea what this is and how to treat it?! Oh and I thought it might just be a goat thing so I checked my wether and he was fine.

What did this end up being? My goat has a white patch here and I’m not sure what to do
