I beleive my RIR froze to death night before last! She was fine when I tuck everyone in & I tossed cracked corn on floor! I went to let them out yesturday AM & she was stiff as a board on a perch all alone! ((she was quite perky until then)) every winter I add different single comb breeds that are cold hardy but, It just seems the rose & pea comb never have a problem! have other people have similar finding?
