I am a new member and glad to be onboard. I bought my little peeps 3 months ago and I have never raised chickens before. As a child, my parents had a few chickens. I have always wanted to have fresh eggs and enjoy the antics of my new feathered friends, so I purchased a few biddies than range in size with one large rooster. My husband had an old dog pen (hunting dogs that he had years ago) and we have somewhat converted it for the time being, but I want something that is more accessible and easier to clean for me and my peeps. I have quite a few questions, but I will start slowly. 1. Is there a way to tell male from female at a young age? I now have 6 roosters and 7 hens. 2. Is there a place where I can get detailed plans for a coop? 3. What is the material in the bottom of the pen, dirt, sand, concrete, wire, or wood? Thanks so very much for your inputs. Any advice will be greatly appreciated. I want to make my fine feathered family happy. This website is wonderful.
