We have two goats that are about nine years old. They are both Nubian wethers and have always been very healthy. We have never had to have the vet over for anything other than their annual shots, etc. They do get wormed regularly and have generally been wonderful, low maintenance pets. However, our one goat Rascal has been shedding out his winter coat, but his regular hair has also been falling out. It looks like his skin is pretty dry and flaky, and we are starting to see his skin underneath. He is still eating and looks the same weight wise. They get lots of grass hay and 1/2 can of goat food each two times a day. I doubt whatever is happening to him has anything to do with our feeding, but what could this be? Is it some type of deficiency? Illness? Does he need something extra in his older age? They also have an outdoor pen and a large run in shed. They get plenty of sunshine. Our other goat looks perfectly healthy and got a beautiful shiny summer coat in.
