What do you do post lambing the lamb
Check to see if there’s another lamb to come out of ewe; ideally let her get it herself
Check for any damage to the uterus eg haemorrhage
Now check lamb; make sure its alive, breathing, give them a rub with a straw; swing them from side to side to rid of any fluid which could be blocking airway; ensure it gets colostrum
