Hi, My chics should be here in the next 2 weeks and I am trying to get everything ready. I have some questions: 1. Should I buy the Grow Gel Plus & Quik Chik? 2. I already have some Chic Starter Feed from Tractor Supply. Do I also need the Chick Grit? I thought I read somewhere that if I use commercial chick starter feed, I don't need the grit. Please share with me what you do with your baby chicks when they arrive.
