Jennym, definately check out that website, it has some good information on mixing flocks.
newchicky57, how is it going on integrating your flocks? Hope well!!!
I wanted to let you know that last night, I was feeling sorry for the three older chicks left on the other side of the divider, as they were looking like they were lonely and feeling left out. I moved all three into the baby chick section. One at a time, checking to make sure it was going okay as I moved each bird. It seemed like they just fit right in. Luckily there was no bullying. They were probably happy to be part of the flock that they have been watching have so much fun all this time! Then after it looked everyone was getting along, I carefully removed the divider to give the flock the full space of the whole brooder. It worked out really well. I guess I also did that because I was worried about there being enough waterers, and feeders, and didn't want to buy more. I have two waterers, and two large feeder for all 19 chicks, which seems to be adequate. Now there is plenty to go around, now that all chicks have access to each one. Anyways, it worked out okay!! Pretty good actually. Just wanted to share. I really hope that you have much success in mixing your chicks! Keep me posted!
