I have been giving my chicks the same food for 2 weeks Durmor & Manna Pro Chick feed mixed together and they have been fine. Yesterday they finally discovered the bottle with the brooder nipple waterer and have been constantly playing with it. The bottle had probiotics for chicks mixed in the water. Do probiotics give chicks diarrhea? They also have the regular jar waterer that they use with just water. I try to keep the brooder temp around 82 on the warm end. There is no blood in the poo and no pasty butt. Any ideas?
