I live in the midlands in the UK and have two horsfield tortoises. My female is 6yr old that I’ve had for two yrs and Charlie my male is 5yr old I’ve had from a baby. Charlie was I’ll for quite a while when I first got him and it took a lot of care, patience and money to get him fit and well. I had to nebulise him and inject , but he’s fully recovered now. Last year I had an insulated shed made with heating, then they began to fight so had to divide inside and outside space . My question is why in this nice weather do they come outside till dinner time then go back in again, especially my female. Has anyone else had this problem?
