If you've produced any number of boas you know what I'm talking about. An occassional baby that starts small, eats but doesn't grow, then starts turning dark brown and it's skin gets "crinkly", even though it isn't in a shed cycle. Most people I have talked to just take them to the freezer when they see this happening. In '02 I had two babies out of about 165 that did this. I know that there are probably a lot of causes for this condition, but here's a success story from a 03 litter:
First the details. I had a "first timer" Bolivian whose two ovulations were spaced more than 11 days apart. Then she dropped a good week early when a huge front moved in. About half the small litter was born preemie, with the white placenta things attached. They didn't make it.
There was one small "runt" that did make it though. She started eating and I had hope. Except she never much grew, and didn't have shed cycles. Then she started turning dark and crinkly. I had always assumed she was born premature, but then I recalled that she wasn't born with that white thing. While talking with a friend we discussed that this could be the result of a bacterial infection. What if the "yolk" became infected during development, hence the digestive system of the baby, causing it to be born small, or a "runt".
With nothing to lose I tried flagyl. 125 mg/kg every three days for a total of three treatments (I dissolved the flagyl in sugar water and injected it into pinks). She then went into a successful shed cycle. With the aid of bene-bac I then weaned her back onto larger prey items. This girl is now rocking! She's eating great, growing nicely, and shedding regularly. Maybe something to try before giving up on that runt.
