We have rain everyday now. One of my chicks doesn't look very happy, most of the time he just sitting in the corner sleepy. Which is why I decided to treat everybody with the Purina Start & Grow Medicated Feed Crumbles.
I went to a chicken chat with a nutritionist from Purina. I'm almost positive that he said you shouldn't swurch from reg to medicated. You can switch from medicated to regular.
