Okay, so you need to try something different. I would try these three things. Thaw the pink in hot tap water. It should only take a couple minutes, not 20 minutes. Then mix a generous amount of Ivory Liquid dish soap, original scent, in the water. Rinse it with hot water, but leave a little soap residue. OR boil water, remove from heat, drop the pink in, leave it a minute, feed when white and rubbery, and still hot. Or try the smallest live pink you can find. For the first two methods, removing the snake's water for two days prior to feeding, then feeding the item nice and wet, may encourage feeding. Be sure to replace the water after feeding no matter what. I would NOT try more often than every four days or you are conditioning the baby to refuse.
