What up with their chin flub?

[charlamanda]

Hi Rae, that's what mine look like and last night we heard noises!!!!! It sounds like a dog barking softly with laryngitis!LOL Every once and a while you can hear the pattern of the adult call, but very softly. It's so cute, for now anyway!LOL It only seems to be the one that's trying to call and it sounds exactly the the chirps I heard outside a few months ago that I had posted with pics of the lil froglets. Oddly enough the one trying to call is one of the smaller ones! Not flub chin, go figure. I've been calling to them and he's answering me, maybe I shouldn't be encouraging them!LOL
