I am new here and new to raising frogs. I read somewhere that frogs should not be released.
I rescued 6 tadpoles from a late hatch in Oct. One frogget died withing a week , two froggets seem to be doing fine..growing and eating and the other two are still tadpoles. My plan was to just save them from a sure death and return them back into the wild in the spring when the adults came out. Shortly after bringing the tadpoles inside we had a freeze and the 50 or so remaining tadpoles died as in the previous year. It seems some of the frogs lay eggs too late in the season for all the tadpoles to make it to froggets before a freeze happens.
I love the grey tree frogs we have around our home and they enjoy my water gardens . We have had many, many tree frogs living near us for as long as I can remember.

Can anyone give more info. as to why it would be wrong to release them? Or, tell me how it can be done safely?

Thanks, BC
