I don't think I'll be getting Dumor again. I used Purina last year and had no issues. I started this years batch with Purina, then grabbed a bag of the cheaper Dumor feed to finish their brooding. Big mistake. Their poo stinks so bad it's like something has died! I just don't get it. Dumor is MADE by Purina - why would it have such a different effect on the peeps???
