I am a soon to be keeper of chickens. I am so excited! I am also a little nervous. I will be getting two chickens this Sunday. One is an Australorp and the other is a Silver-laced Wyandotte. Both of the girls are 2 years old. They are being rehomed to me by their present owner because he has gotten new chicks. Can anyone tell me about the temperment of these two breeds, also are they hardy? Since I live in northern Vermont, the winter cold is a concern. Their present owner lived in a less rural area than we do and their hen house was in a more sheltered area. My husband and I are converting our "Ice Fishing Shanty / Garden Shed" into a hen house with a fenced in run. There are also fox and racoons that our girls will need to be protected against. Your suggestions would be appreciated.
