Well i think i figured it out.. no illness i dont think.. I dont get the chickens out much, i feed and water, leave them in the cage. well as i have the roo in the house in my hospital cage i noticed when i gave him some meal worms, he wasnt hitting them when he was trying to peck them! i fed him, same thing with the chicken food! He cant see the food!! Its his oversized crest, he cant see what is right in front of his head! he still is on antibiotics for another three days, im medicating a couple other cages of chickens. Ive got them in cages in the shed until i get their run finished outside.. Does anybody know a good food to feed them? Right now im feeding nutrena unmedicated chick starter. my oldest chicken is 4 months old, then the bunch of babies are about months.. I think the food isnt good for them, i have a few thin chicks that were doing great before i put them in the shed. I had to move one of them back in because he completely stopped eating, he will eat meal worms and everything but wont touch the chicken food. Any ideas?? Thanks for all your help!
