I read a post on here were someone feeds their chickens more than one type of food. Scratch and a basic feed. I understood scratch was a treat. So should I be feeding my birds something more?? Right now I feed them all chick starter. Next paycheck I will be buying the girls the laying food now that I have gotten my first egg. Sometimes they get corn as a treat, and sometimes a bit of table scraps. Is there some thing else I could/should be giving them. Also while I am here... how important are oyster shells... should I invest myself in some of those as well?
