Thanks, I knew I wasn't seeing and hearing things. Here comes another question....I also have chirpped to the froglets. Some comepletely ignore me while others have a very strong reaction. Several have turned directly towards me and will open their mouths widely, as if they are trying to call back, but nothing comes out. Every time I chirp they will do this silent open mouth back. When I pick the little guys up, during the day, and chirp to them most will settle down, tuck their legs in and nap. It seems to ralax them considerably, otherwise they just want to jump away.
