In that case, i'll keep up the usual routine and go from there. So it's alright to take one out for a while and feed them? I don't want reintroduction problems.
@Keiko The Pig okay, it's good to know this behaviour is not out of the usual. Yes, I guess that's why my poor boy got those little scratches/wounds. In the meantime, I guess I'll just wait and see mainly.
It is alright to take him out for feeding, as long as both are eating at the same time and the top pig can't smell extra food on the other.
