Once Muppette is spayed there should be very little chance of them fighting as baby bun will always know that Muppette is her mum...
And I thought that if - as you seem to have done, Babsie - we give them a big run, Baby might teach Muppette how to create a burrow as the instinct must be strong in a (half) wild one. Of course, I'd probably live to regret the teaching of that particular lesson!
I have to say it has been fascinating getting to know Muppette. From getting her used to me as a trusted source of food, from her escape attempts... especially the third most serious attempt where she was missing overnight but still made her way back close to where we were. I thought this might suggest their "homing" instinct is quite strong and immediate. To watching her in captivity - I can see how easy it would be to litter tray train them as she is very specific as to where she deposits her hard droppings and pees. She's very clean.
She doesn't really like being stroked if I stroke her sides or back but, as someone said earlier, they are quite amenable to being stroked from the nose back to the ears. Which is interesting: is that because a hand coming in from the side or above is threatening to a prey animal whereas they cannot clearly see a hand that is in front of them and which goes back between the eyes to the ears? So they don't perceive it as a threat?
I didn't know that - like hares - they ingested their first droppings to wring out all the nutrition from them. I did know that about hares because I raised a wild hare from 48 hours old to release weight several years ago... and found him (or her) a nice, safe release site. I was careful to expose the hare to only the bare minimum of contact during the 3 months and s/he stayed very much a wild creature albeit one who was happy to accept room service especially if room service included the occasional peapod. Hares are fascinating creatures - not social at all - and even now very little is known about the way hares "mother" their young which are born fully-furred, eyes open and are left on the surface from the moment they are born.
So having Muppette is proving very interesting and I'm looking forward to seeing the babies properly. It was warm in the poly tunnel today so the baby / babies have pushed back the straw so I can see them but it's too dark in the cave to get a photo without using flash which I don't want to do.
As previously, I really appreciate the advice and suggestions that you're all giving me.
