My 8 month old went through a fast after a stressful month. He had gotten him self stuck and turned around in a resin log with only one possible exit and a couple smaller holes that he could just see out of. He was in their for over a month and ended up shedding inside. But then still wasnt able to get out and you could tell he was trying cause every couple of hours he'd be in a new spot poking around the smaller holes. I ended up having to carefully break him out one small piece at a time and he got pretty freaked out. Waited 2 more weeks before i even tried to feed him and he didnt strike. After 3 more tries and pray half the size that he was getting before this all started he started eating again like a champ. Im thinking maybe the stress of the RI injections and the shed was alot in one month. One thing i've learned from this forum is to be patient and make small changes.
