We feed our adult Sebrights high quality layers pellets and roller oats and we also let them forage in a bigger pen often and we feed our baby chicks chick crumb but it is very important that for the first few days you grind their food into smaller bits so they do not choke. Food for 5 chicks/adults, chicks (an average of 1 euro a week for 15 weeks), adults (about 2 euro a week for the rest of their lives).
