Hi everyone! Im a new chicken guy from southern PA...right on the PA/MD border. I converted one part of my barn to a chicken coop and Im just 6 days into raising chickens. We have 3 RIR's, 1 Barred Rock, and 1 Silkie (just had to get her!). Anything I need to know/do/not do/etc!? Their coop is on concrete floor on the back 1/3 of an addition to the barn. Its 8x10 and could always make it bigger. The girls free range under me and my kids supervision and go to town eating up everything. The girls are 5-6 weeks old and hang pretty darn close together in the coop and out back. We have a big dog (Brazilian Mastiff) and some killer outside cats. Any advice is welcome! I will have to get some pics up soon!
