I took in 24 gray tree froglets last fall & I'm trying to figure out when's the best time to let them go? My above ground pool is now a frog pond & I've fostered hundreds..thousands of tadpoles that hadn't morphed b4 the pool froze solid, as well as, several hundreds frogs & toads that morphed too late in the season to survive, which was the case with the 24 gray tree froglets I took in & still have.
I live a top a mountain in Pa in a town that's bordered by NY & NJ & as of 5/11/13 the tree leaves haven't fully come out. The days are fairly comfy between 60's- low 70' s, but our nights are still cold ranging between upper 20's-upper 40's. I know Grays tree frogs are hardy lil fellas, but I'm afraid releasing them too soon, w the nightime temps mostly in the 30's & 40's, may throw them into a false hibernation or just screw them up, since I didn't hibernate them. I kept them between 68-72'F and fed them regularly. About half of them are at or close to full size, the rest range from slightly below an inch to somewhere between 1-2".... sadly about 1/2 are missing legs, I'm not sure wether that was due to morphing so late in the season, the nasty bitting creatures in the pool, lots of the tads were missing some or most of their tails from them, or just pollution, which is odd for this area.
Any advice or suggestion would be welcome & appreciated. Thanx
