My chicken friends are new to me and reading the emeergencies really scares me. I have 12 two year old chickens and 26 chicks born in September. The big girls liv in their own coop and the chicks have their own coop. I keep the litter clean and give fresh food and water about every 3 days. Is there anything I should know to do? They also free range over 2 acres ( the big girls do) and get a lot of leftover food and veggies.
