Dr. Falconer,
Thank you for your reply. As to the possibility of grain having an effect, I do use approximately less than 25% of grain in my homemade food for the fiber (male prefers peeled boiled red potatoes, female cooked pearled barley) and this does not seem to induce eye discharging. So as you say a mystery I guess it will remain. I worry about them getting the proper vitamins too so I give them a supplement but only 1/4 of what is called for per day, anymore than that and their eyes goop up as well. Again thank you for your thoughts, I guess I'll keep doing what I'm doing.
