So... I love, love, love my chickens, ducks, and BYC. I come to you, to humbly ask for guidance. I love hay for my coops and runs, for stacking as insulation. Problem? I am SUPER allergic. Hives, asphyxia, I can barely see allergic. Shame too, it is easier to clean up in the yards and is great mulch for my garden. I want to love pine shavings more. They keep it SO much drier - especially in quack shack. I have read that they add a lot of light, fluffy texture to a compost bin or heap. I just really hate the mess they make in the yards. I use tractor style housing for both enclosures and have an enclosed yard for them that they range in during the day. The area around their coops is littered with pine shavings. I have tried lining the area with tarps, creating giant pans to rake the coops over. No amount of raking keeps the yard clear of them. I think I prefer hives, and will go back to hay today, if I must. I have read the books, but I wanted to hear from people with experience as well, and y'all are fonts of great advice.
