Please, please be kind as I’m distraught, but looking for opinions /answers.
Yesterday I found one of my Ibera dead (8 years old) and just now I’ve found a hermanni dead (5 years old)
They’ve been outside for the past 2 months, fresh water twice a day, bathed, only fed weeds grown by myself and odd bag of salad . They have cold frames, wooden boxes and stone hides as well as hostas, hebes and grasses to hide in. They have calcium and nutrabol a couple of times a week.
They all came out of hibernation fine. They don’t come into contact with each other apart from when they are in separate shoeboxes in the hibernation fridge.
What’s happened? Is it this crazy heat? They have sun in the enclosures in the morning and shade in the afternoon. They’ve all seemed really happy to be out so long.
I’m worried about the others... I’ve fished an odd cat poo out, I’ve dug up foxgloves that were elsewhere in the garden, what has gone wrong?? All others have been bathed and are feeding fine... but I’m terrified...
