I have 5 2-3 week old chicks and I'm planning everything for their coop and run. I've been leaning towards the deep litter method for bedding inside the coop using pine shavings and straw. However, I've read that it can get too hot during the summer. So, my question is, if I start the deep litter in June starting with 6 inches and building up to 12 inches, will it get too hot in their coop? I live in the midwest and the weather shouldn't get higher than 90 degrees at the most. If so, what do I do for bedding until it starts cooling off outside? When should I start the deep litter process if I wait?
