We got a pair of Blue frogs that were just approaching juvie age & size................They are just approaching ayear of age and are deformed in many ways. We had hoped that with care & pampering, they could possibly outgrow the issues. Only one of them is healthy enough to breed. The other is severely deformed. It has scoliosis that seems to get worse as it ages. A major under bite (fangs always exposed). And has the semi-paralyzed front arms & feet.....and of course the lean.
When you pay $300 for a frog, you expect it to be healthy. You at least expect the seller to respond to any inquiries. I gave up long ago trying to get a respons, so We just deal with it.

What sucks is we will probably have to euthanize the one frog.....after a year of caring for it, it's not easy.

As for selling adults.......we keep records of when eggs were laid and can tell you the age of every one of our animals except for those purchased from other sources (not many of those). We don't power breed our frogs and make sure that if & when sold, they are as healthy as possible. We plan for that to be one of our points of sale for our little business. It's also a matter of Pride for us.
