Thank you to everyone for their comments.

Regarding question 22 (oops!) they are usually fed in a large box. I occasionally pop a few locusts in to give them something to do but it's not very often and they don't last long enough to do much anyway.

No fecal testing, no. Got some Panacur we use on the reps sometimes if fecals prove positive but wouldn't use it without knowing. It's a good idea and might be worth pursuing. Not the easiest thing to get done where we live, sadly.

I've thought about quarantining but my wife thinks I'm worrying unnecessarily. Couldn't hurt could it.

Been trying to get some profile shots but as soon as the door is opened they see it as an invitation to jump out and have a play! Kikka does appear asymmetrical, I will check this. She is the most energetic of the lot. Always leaping about and causing havoc trying to figure out how to escape. I always worry about injuries but I don't know what to do...how do you stop a frog being a frog?

We did try a bath in warm water but she wasn't too happy about staying put!

I'll try and get more revealing photos and think about the suggestions.

Many thanks for your help.
