I'm so excited - after years of wanting to do this, I finally have chicks! We bought 12 from Tractor Supply - two Buff Orpingtons, 6 Barred Rocks and 4 White Leghorns (though one has feathers on its feet?!). I'm feeding them Dumor Chick Starter/Grower 20% and have added, in another dish, some NutriSource Chick Grit (crushed granite). I'm reading several food related terms I don't know - layer ???, mash? Also not sure if my feed is medicated? Anyone familiar?
