I've read a few posts that talk about how flat roosts are better, as chickens have an easier time keeping their toes warm. I'm wondering just how big of a deal this is? This is my first year with chickens, and they live in a 50s-era coop (dirt floor) that came with the house I'm renting. Their roosts are round wood, about the size of a broomstick and are probably original to the coop. We're in Colorado, so it gets pretty cold but not humid. The coop has open eaves at the top and isn't insulated, but has deep litter and south-facing windows. We have 13 LF pullets in about a 20x10 space. I'm not really in a position to build new roosts, but I'm wondering if it would be possible (or even a good idea) to put something over the round roosts? I'm thinking of maybe that gray foam pipe insulation - would they eat that? I don't want to create a new hazard or freak the chickens out by changing things, but I also don't want any frostbitten toes. I'd love to hear your suggestions and experiences on this - thanks!
