Glad to hear all that! I imagine there aren't very many folks out there with much egg-eater experience, though.

Info that might help puzzle out whether or not there is a chance for recovery:

1. What do you THINK caused this? (You said you had an idea)

2. When did you first notice evidence of something wrong?

3. Did that something appear in both snakes at the same time? Or first one and then later the other?

4. How fast have they "gone downhill" since you first noticed something wrong?

5. How much worse is the second one than the one shown in the vids?

6. What steps have you taken to try and correct the issue? (ie: extra feedings...calcium supplements...change in diet...medicines...change in environment?)

7. Did your vet have any advice to offer at all? If so, what was it and were you able to follow it?

8. Have you seen any signs of improvement at all that might indicate a chance to turn it around?

I don't know if we have any resident "egg-eater experts" around...but hopefully someone will be able to help you come to a reasonable and humane decision.
