Thanks for uploading pics and weights! Try and get a feed that has at least 18% protein, it's also generally advisable not to mix corn in with their feed since corn is low in protein. RIRs tend to be a somewhat smaller breed, plus yours still have growing to do. Best of luck!Hi, I'll upload pics after this reply. So I just checked there weight. The smallest on is 0.7 kg and the biggest Is 1.1 kg. We feed them mixed fowl feed and crushed corn in an open feeder. We have other chickens on our farm aswell which all have access to feed any time they want itView attachment 3049405
