Katie and Jim noticed how much fun their son Finn had collecting frogs and toads in the backyard. They started dreaming and planning about starting their own business.  Jim and Katie were already raising Red Eye Tree Frogs and Auratus Frogs.  Finn’s Frog Farm was officially established in April 2020.

This crazy passion for frogs has already been passed down to their son who loves roaming through the yard looking for toads.  He always wants to hold them.

Eggs, Tadpoles, Frogs and Bugs

It has been an amazing adventure to raise frogs from tadpoles and see them continue the cycle.  Although the picture to the left looks like the tadpoles they are still in the egg.  The red lines that are coming from the egg are the gills and the way in which they breathe.
