Can't help you much with cold care knowledge. I am in Central Texas and except for an occasional freeze , which they tolerate very well, our winter temps are usually not freezing.I have two Buff Orpingtons that I have had for 4 years. I love them
It happens.
I bought two, what I was told were Gold Lace Wyandotte chicks. I never paid too much attention, I figured eventually they would grow to look like Wyandottes. Like a year later someone on BYC told me they are really Brown Leghorns. Well pooh. They are really great egg layers. :)
Sorry you lost Princess. I have a Princess too. But she is a Rhode Island White. At least that's what they told me she was when I bought her as a chick. :)
