Is frostbite avoidable without electric heating? Should I add heat to my coop?

That why I wear cheap cheaters (glasses)

Yep need a pair for sure.

I had 3 cockerels I needed to do something with but I've only got 2 left.One is going to replace my rooster who is 3 yrs old and the other one I'll give away.They look and act just a like so I can't decide which one to keep

What do your girls think? Do they have a preference for one over the other?

And how old are they now? (as in, how far into the hormonal crazies are they?)
