So I've never had chickens and I got 12 red pullets and 2 pekin ducks. Got them so my 6 year old could gather eggs and sell them to start her some responsibility and beginning to understanding the concept of money and work. With that being said I have built a coop that's is 4 x12 and have 8 12x12 laying boxes off the back. They are approx. 5 to 6 weeks ok getting black feathers in their tails. I bought them from tractor supply an was wondering what kind they might be. I'm from middle TN. Needless to say I could use some advice generally speakin about anything to do with these pullets to educate myself. Here is a picture of my coop.
