Hi Danny, Sorry about all the questions,but how long have the girls been together and is it 2 or 3 sows you have?. I am not quite clear whether the sow that is whimpering is with her sister,or whether she is with 2 other sows who are sisters?..If it is the latter,it is possible she is being bullied and the whimpering is a fear noise.As she is eating and running around it is unlikely that she is in pain.Do you weigh your piggies?,weight loss would be an indication of stress.Sows hate being on their own and really need the company of other pigs,but sometimes a sow can be so bossy by nature she will terrorize her companions.A small 8 week old baby would be an easy target.Hopefully.bossy boots will calm down soon.If the baby has recently been introduced to 2 sisters,there could be a bit of jealousy,but this should calm down,and as the baby grows she will be able to defend herself.Just keep an eye on her and make sure she continues to eat,and does not sit huddled in a corner.,and weigh her on a regular basis,
Mary
