Wanted to share my experience as there have been lots of questions lately. I bought 3 BO's and 2 Production Reds 10 days ago. My mom brought us 5 EE babies yesterday. With much trepidation I put them all in the brooder together. They are exactly 11 days apart on hatch dates. My first five seemed so BIG compared to the new guys. Weelll....... no worries. The little guys are not only unintimidated by the big guys but seem to think they are in charge. Everybody is eating, drinking pooping and napping together in a 2ft x 4ft stock tank in the dining room.
