Two weeks ago Ferdinand looked like this . Before the show and before mites. Now he looks like this... He is experiencing runny diarrhea like stool . He is also breathin funny like a h-h eh . His comb is red and he is eating and drinking fine. I have given him terra vet 10 for two days , 1 1/2 tsp to 1 gal of water. I purchased vet Rx and probiotic powder , but have been weary to administer. I am scared for my boy and need life saving advice .
