The Chantecler, a breed developed in Canada in the early 20th century, is one of the most notable cold-hardy birds, and it provides an exceptional source of both eggs and meat. Buckeyes, originating from and named for the state of Ohio, are also well-suited to long, snowy winters. Some other breeds developed for winter egg-laying include Wynandottes, Faverolles and Dominiques.

To avoid frostbitten birds, apply petroleum jelly or moisturizer to their wattles and combs a couple times a week.

With these tips, your avian friends should be well-prepared to weather the chillier months.
