Mouse Tails
I used to want to get all of the babies to live. This year I euthanized any corn that would not eat FT or Live. I tried scented and unscented multiple times, after that they meet the freezer, and will meet the MBKs, once I get the annulata needed to trade for them eating. What I used to do for corns, and still do for alterna, and will probably do for annulata, is force feed mouse tails. I feed about 1.5" if the tail, and take the part of the tail closest to the body of the mouse. That part is more rigid and easier to push down the snake. You do have to be gentle and coax it down, but once you get it past the mouth, the snake will usually keep it down. If you do not get it past the mouth, it may spit it back up. Most would start taking some form of pinky after 4-6 mouse tails. If you want to "save" any I would suggest mouse tailing, heck I did 17 alterna babies last night.
