HELP!!

My first clutch ever pipped on day 52, 7/1 (weird because it incubated at 89 degrees). The lesser came right out of its egg but hadn't absorbed its yoke. I put it on wet paper towel and left it be. The size of the yoke went down about half and today 7/4 the sac smelled rotten and hadn't reduced in size since 7/3 so I tied off the cord and snipped off the yoke. He/she is 40 grams and alert and kind of active but no where near as active as his clutch mate (female normal). I did some research prior to snipping the yolk off but am still unsure about what to do next. Any response helps, especially if you have done this before. Thanks. I attached a picture of the yoke at its most absorbed state and a post snip tied off cord.

That should dry up and fall off after the first shed. I had a similar hatchling this year and I assist fed her a pinky the day she shed just to make sure she had something in her. After the assist feed she took a live hopper mouse on her own and is doing great now.

Ok great. Thanks for the response!
