So i think out figured out the problem with my pied. Humidity.
What i have done is lower humidity right down and i now keep her on paper towels. Her water bowl is kept away from the heat pad. she now looks great and in fact has started eating again after a period of about 5 months.
Has anyone else heard of humidity creating this condition. All my other balls are doing great in a humidity range of 50 - 70%.
I just saw a little red spot on my butter. I checked the humidity and was in the 70s. I got to drill some more holes in the side of the container tomorrow. Hopefully that resolves it.
I had a similar issue with "water blisters" on a girl that liked to hide in her water bowl (all the time), instead of her regular hides. I replaced her bowl with one too small for her to fit into, did a week of betadine soaks, and the bumps were gone in two sheds.
