Turkeys And Chickens together?

Thanks for all the info and opinions. The place I read about not having them together was in the Storey book. The ones I had together outside were two older turkey poults too large for the cage I had inside with the rest. The chickens in there were also poults of 10 and six weeks old. The turks are now out in their own condo. I also had a chick in a cage inside next to the turks. He was the only one who hatched and was so lonely and chirped so loudly, but was too small to put in with them. He seemed much happier next to them and quieted down. He ended up with a companion 21 days later when another only hatched. I have this broody hen who keeps trying to hatch. I candled the eggs about day 18 and each time only saw movement in one egg, so I popped it into the incubator to give it a better chance to live and both times they did hatch. She is on another batch now. Started out with 21 eggs and is down to 6. I candled them the other day, but couldn't detect any movement. Hard to tell sometimes with brown eggs. They should hatch Friday, if at all. If not she is going back in the coop with the rest of the flock. Three times trying is quite enough and I need the hutch where she is setting for the mother rabbit who I need to wean from her babies.
anyway thanks for the info.
