going off food/water
this is another thing to bear in mind, please. the reason my star has the issue he does now, i believe, is because moo.moo has been guarding the sipping tubes. when pigs pigs need to drink fresh water, and are denied access to it, anorexia can develop [i've been reading about this on GL site].
in addition to the water guarding, he was chasing and mounting the two other boars every time they even moved in the direction of sipping tubes!
they are all separated at the moment, for stars's well-being, until star resumes proper intake of fluid/foods. rest from the stress caused by moo is imperative. maybe they will live this way on a temp basis, or else it could be longer-lasting.
even though the boars were not drawing blood, and were well within the normal behaviour range, if someone is unable to eat or drink - it can become serious.
star is eating and drinking some, and making poos, but has little interest in pellets.
