Hello there, I currently have 5 baby grey tree frogs. I had 33, they have hardly grown and honestly it pains me to know I've had this many die on me. At first it was due to the weather changing and insects outside being scarce and a lack of a heat source but now they've had heat majority of the time and food every other day. However they do not get Calcium supplements. I'm honestly scared I'm going to give them too much and kill them that way. I really don't want the 5 remaining to die but I'm afraid they will so I'm desperate for any help. Maybe it's a lack of calcium so I was wondering how much a tiny tiny frog would need to be exact. Also is a heating rock going to burn a frog the size of a penny? Also I feed them medium sized cricket parts because pinheads never work out.
