>>What are y'alls thoughts on "runts" of a litter? Will they grow to be smaller adults? Is it a sign that they are some how unhealthy?

I've never owned a "runt" but I had a female that ended up being a dwarf. She was an 02 and had some sort of tail abnormality where there was a very drastic change in girth rather than a nice even taper. I posted pictures years ago and others mentioned seeing the same issue with other dwarf indigo's.
At around 3 years of age she was barely over 3' long and nearly as big around as my wrist.
Here are a few pics.
