Does anyone have a remedy?? My black copper has a huge swollen chest. The size of a soft ball at least. I have watched this increase for 3 weeks now. Originally I saw an earlier post on BYC with someone having a problem like this one. The advise was a mixture of olive oil and water. Then an eye dropper of this daily and then massage crop each time for up to 7 days. I have tried this method and still using it to no result as of yet. I had a vet here on my horses that looked at him and didn't really know what to do or what it was. He was a large animal Dr so I am not to surprised but thought he could make an educated guess. He advised that I should try to take feed from him for 24 hours and see if it made a difference. I have taken the black copper away from feed. It has been 24 hours now but I see no improvement in the swelling of the crop. I don't know what to do. He is a little over 4 months. Maybe its just me but he seems to be weak today now. I don't know if I should give the food back to him or wait longer or what. Does anyone have any advise or know what I should do? Am I going to loose him??
