Hi my name is Rob, recently built my first coop and began raising chickens for both meat and eggs. I strted with 6 day old chicks, 2 each rode island reds, white leghorns, and americanna's . Just added 11 more to the flock. I was able to talk my good friend Shawn out of some of his prize birds, 4 partridge cochin hens and 1 rooster. 2 welsummer hens. And 4 young black copper marans . I just wanted farm fresh eggs and meat for my family. I have a young grandson that has been totally mesmerized wathing the chicks grow up. So far no problems integrating the older chickens with the 3 month old marans or the 6 week old mixed chicks. I've built a waterer using the 360 nipples that I hope will work out as cleaning a waterer daily just doesn't sound like fun.
