I think I read this when my chicks were tiny and now I can't find the thread. I believe I read that Purina food makes the poop smell more pleasant??? Well, not pleasant but not as bad as some feeds? Any suggestions? I am currently using what Tractor Supply has sold me. I just read at the bottom that it is manufactured exclusively for Tractor Supply Company. My chicks are 6 weeks old now and it says on the bag that the Dumor Chick Starter/Grower 20% that it needs 15% at 10 weeks. Any input on what I can use next based on their needs and also smell? Thanks!
