Wow; that is awesome. I love frogs; they were my first herp love, and they are such cool little environmental barometers. It is awesome to rescue eggs, no? A few years ago I took in some wood frog eggs from a puddle (vernal pool) in the woods that was drying up; a day after I took them, the puddle was bone dry. I kept them in naturalistic conditions until they morphed, and thn released them.
It is a great feeling to help froggies.
