@Arella Mae,
have you ever looked under his eyelids at the surrounds of the eye socket. It should be a rosay pink color. Is that a whitish or grayish color?
Worms arent the only thing that give the dull coat.
IS your water acid or basic? We have to watch copper toxicity with the sheep, so weve run a separate filter with limestone bedding. It kicks the pH up to about 7.5 and the sheep just blossom.
I dont know whether horsesget coppwer toxicity . MAybe cowdoc is around , can we send PMs yet?
