Hello and help please

[da baby]

Hello
i have 2 red and black walking frogs i was wondering how to tell if one is female and if so how do i know if she is having baby frogs

Only male frogs sing. Females can sing, but usually don't. If you frog sings/makes noises it is most likely a male, if not, it is most likely a female. Sorry, but i am not sure how to tell if it is pregnant!
Have a hoppy day !

I assume we are talking about the Red-Banded Rubber Frog of Eastern Africa. As far as I know sexing is the same as most frogs, males sing females are larger. Most likely your frog is not gravid.
