Been raising goats for a few years. Every year one kid out of our 10 - 15 kid crop will chew its rearend and under its tail until it bleeds. It happens with both sexes. We were told it may be lice. If that was the case wouldn't the twin have them too? They always sleep together. We have been treating them with a hydrogen peroxide cleaning and some type of antiseptic. But they keep it up. Usually it stops around 4- 5 weeks old. We also dust them with diatomaceous earth.
Anyone know a cause and cure?
