Kristy, thank you for your response. I hope I don't sound snarky, I really don't mean to, but I explained in my post that I know better than to put them in with my tree frog and that my preference was to return them to the wild. I was just concerned that during the time I was explaining this to my husband, they warmed up so much that plopping them right out into the 38 degree temps would be too much for them since they are so tiny. I don't know much about baby frogs in the wild. I set them up in an extra tank and put them in the garage to reintroduce them to the colder temperatures without shocking them. The temps are supposed to be the warmest for the day around 2:00 this afternoon, I'm planning to let them go then. I love your idea of putting them in the compost pile!
