Hi. I'm not aware of any reason why frogs from locally collected tadpoles should not be released back into the area where they were collected. I raised nearly 60 rescued Grey tadpoles last summer, and released 52 of them back into the wild. I released them into nearby wooded areas, after raising the froglets for several weeks, as I felt that the newly morphed froglets would be more vulnerable to predation.

There may be some reason why this was wrong of me, but I don't know what it would be. I don't currently have any other animals, so they would not have picked up any novel pathogens.

Since you have them in your yard, I don't see that it would be a problem to release them in the spring. Were the tadpoles in your yard, or did you find them somewhere else?

It's very important that you dust their food frequently with Calcium/vitD powder, and a vitamin supplement, but not at the same time.

Maybe someone else with a different perspective can chime in on why it might be a problem to release them.
