I've had two babies me and my girlfriend have hatched at the end of July 2021, they've both been completely fine before no behavioral or physical issues, they're fed repashy every two days where they both have eaten completely fine. The only problem so far has been that one has been slightly smaller than the other (being the one with the recent tail issue) but I have monitored this by watching for bullying and hand feeding the smaller one with the recent tail issues. They're in a bioactive exo terra with a fogger and a heat lamp because of how cold it can get here, but I've always monitored temperature and made sure they're stable with the help of heat lamps and heaters. The problem occurred today when I took the smaller baby out and noticed her tail had been crisp and dead looking, I considered it being from the other gecko attacking this one but they've never shown signs of that before plus they're both girls. My second thought was that maybe she had pinched it on something or maybe the heating failed and it got too cold. The gecko doesn't seem to be in any pain and is completely happy and moving around with ease, if it wasn't for her obvious tail issue I would think that she was fine. I'm asking for help for just what to do next, the exotic vet in my city is closed right now so I cant take her there, I was wondering if it would be smart to assist her with dropping her tail or what.
