Welcome to BYC! I recommend using 1/4 inch hardware cloth (very strong mesh wire) instead of chain link, many predators can reach thru chain link and grab a chicken. Best of luck to you.
Welcome to BYC, and X2 on the hardware cloth. You've received some good links from other BYC members. What kind of chickens do you have?
appear to consist of (1) Australorp (Regina - definitely queen of the roost), (2) red hens that are likely Red Sex Links or maybe Production and (2) scrappy hens that could be EasterEggers or maybe Legbars.
