I kept my c section ewe in until her stitches came out several weeks later, as it wasn’t easy to catch her in the field once she went out. Recovery was pretty straight forward- she had a week of daily pen strep injections, cleansed normally, reared her twins no problem. But I should have culled her- I took a chance and put her back in lamb after hearing conflicting advice on whether to tup her again. She had a great set of twins but died from a haemorrhage 6 hours after lambing- we think there was a weakness in her uterus from the stitches. So as long as your ewe rears her twins I would cull her at weaning.
