I went out to feed my babies today when I came home from school to find my smallest stag, a black Sumatra/Phoenix cross, walking rather odd. I picked him up, thinking maybe his foot was cold from the weather, but instead found his throat area very swollen and hard, and warm to the touch. Could it be crop binding? What should I do? I saw on one thing when I was researching that perhaps I should eyedrop some mineral oil down his throat and massage the hard part. Could it be something else? I'm confused and really don't want my little Elvis to be in pain.
