I want to make sure I do everything correctly for my chickens, so I have a few questions. My chickens range in age of about 2 months to 3 months, and I have new chicks that will arrive soon. My new chickens hang out in my basement in a metal brooder until they are old enough to be outside alone. I have a mix of roosters and hens. 1. I started them with a medicated feed, but have switched to a Purina brand that is for mixed flock, and it is supposed to be free of GMOs. It is still a crumble feed. I have been told by someone else that I can stay on crumble feed and just provide oyster shell for the hens to nibble on. I was told the layer feed is harmful to roosters. What feed is best for a mix of roosters and hens? Also, do I need to provide grit if I am not giving whole grains. 2. How do I handle the poop in the run/roam around area? It is a grassy (well soon to be bare) area. Do I need to spray it down to dilute all the poop? Do I just leave it lay there? Also, how clean is considered clean? Do I need to remove the perches and scrub them down? My coop has a removable bottom that I pull out to remove the soiled hay each week, but don't spray it every time, because many times there is no poop stuck to it. I can only pick up the mess in the nesting boxes. 3. In the winter what do I need to do anything to keep them warm, or is being in the coop warm enough? I live in KC, MO, so our weather varies greatly from day to day. 4. What is the best bedding to use in the coop and nesting boxes? I currently have hay, but I have seen others using pine shavings. I'm sure I have other questions, but that is it for now. I have read through many things, but I am a very anxious type person and want to make sure everything is great for my chickens.
