I have an adorable flock of 6 pullets (2 RIR, 1 Sultan, 1 Cochin, 1 Buff Orpington and 1 Amerucana. These ladies are 13 wks old. What chicken type of chicken feed do you give this age chicken? I stopped giving them the medicated starter feed at 6 wks and was giving them game bird developer feed given to me at the feed store. Now I went back and they told me to continue giving them the medicated starter feed till they were laying? I am confused?! What do some of you use?
