My sow is an older gilt. It appears our pig is bred. We have not had this happen on our place yet. It is cold here and she would be due in March, which is still pretty cold. When she was young she ate all my chickens, because i did not consider that it would be an issue with all the them in the warm place.... anyhow, i am now a bit concerned that she will eat her litter,because she did that and because she is older (2 years)before she will have babies, .
