hello I have six 1 week old ladies (4 BR, 2 RIR) they are watering fine and they find the feeder just fine also, well heres the question, 1. I was going to remove the paper towel tonight from the brooder and just use chips is this right timing? 2. they are on purina start & grow (medicated) do they need grit? or when if so when to start it, i know once they start going out and free ranging i have to offer it. do they need it sooner?
