Our yearling pack goat - Bourye - had his head stuck in his feeder. He may have been there for multiple hours. When we got him out his back hooves splayed and he is not walking upright- looks like weak pasterns. It is just his rear hooves as he was somewhat up on them in the feeder He is walking, eating and drinking but we are worried they won't straighten up. We have done some reading about selenium/copper/zinc deficiencies but this seems to be more from trauma. His twin brother - Whiskey - has no issues and neither have ever had hoof issues. Image attached. Any ideas or has anyone else ever seen this?
