@autumnhearth I couldn't figure out how to reply to your comment on Olive's picture so I'll just reply and attach pics here! My girls did great over the winter, I don't use artificial heat and only had a few with large combs that got a teensy bit of frost bite on the very tips of their combs but it was just superficial, it scabbed and healed right up. Olive the speckled sussex didn't have a problem. Here's some recent pictures of her...
She really turned out to be a lovely hen. I love her shape (she's really proofed up due to the cold in the middle pic so don't judge that one lol). Her feathers are so shiny and the black in them highlights a gorgeous green. She's a little less speckled than I'd hoped but I've heard new speckles come in at their first adult molt
What a beautiful bird! Speckled Sussex is on my wish list, but probably not until next year... I wouldn't mind having one like yours though!
