A bad shed is a sign it had poor husbandry. You need to get that on point.

If you have signs of RI and vet visit us in order. If you truly believe it is from the bad shed I would get things on point so the next shed goes well.

Not being there I can't tell you exactly what to do.

Any other signs of RI like mucus, pointing head upwards, yawning with visible stringy saliva?
