Why don’t I remember this? This is delightful.
I would connect the waste tube to her food tube. Maximum misery.
Brutal but effective, And none of that bitch mare Stress
Actually I believe so strongly just cause of the layout of the bag is very similar to the one I posted
Looking at it in more detail, they incubated a premature lamb for 4 weeks until it was strong enough to survive outside the womb. They’re still working on the process for growing an embryo into a foetus and beyond into a viable organism.
The fluffy bag’s a good match, but it’s missing the critical component of a placenta analogue so the foetal foals can get oxygen and other nutrients and also expel carbon dioxide and other waste products.
In the lamb photo, it’s the big red tubes inside the main big plastic tube.
The endless wheel of suffering
Just for kicks, say you know what hun you have have one of your babbehs come visit.
Bring in the munsta babbeh 
let her know how well hes doing and how munsta is getting all the miwkies and toysies, the other babbehs nu get miwkies (this isnt true of course we need healthy feals for whatever purpose but… she dont need to know that)
Maybe for the mare, but then you risk compromising the usefulness of the milk she produces, which could then affect the potential sell value of the foals.
