I HAVE 6 SKINNY CHICKEN they have dunmor chicken pellet all they want . then at noon I give them a flake of alfalfa grass hay mixture three o'clock they get 1 1/2 lb can of scratch 1 1/2 lb of black sun flower seeds. They were wormed in dec and treated Duramycin once (in NOV. than he treated with corid for coccidoisis in dec. Are they getting to much scratch? I keep the coop clean as i can in winter, change wood shaving every two weeks completely. under the roost every two or three days but i stirr it every day never smells. that get fresh water daily! So Happy about that! What Iam I doing wrong that I have skinny chickens?
