You will find that some chicken breeds suffer the adversities of the falling temperatures in winter more than others.
Beyond their resistance to cold, Australorps give you a whole lot of eggs. You can get as many as 250 eggs per chicken in a year.
Orpingtons owe their cold-tolerance to their abundant fluffy plumage. You can get around 200-280 eggs from them in a year.
The Dominique breed was built for cold. Hens are decent layers that can give around 150 to 200 light-brown eggs in a year.
If you are a poultry farmer or a chicken owner living in a temperate region, you will benefit from having cold-hardy chickens around.
