Merging a flock

[CDennis]

I have two older toms I am keeping for breeding and I sent 3, 6 month old birds to freezer camp today. Out of the freezer camp bunch there was a Jake, and all the rest of my hens would hang out w/ him and not the older toms. Now that he is gone, what is the best way to merge the two toms and 4 hens into one flock? Everyone if friendly, but the young ones roam everywhere (aka places like my husbands truck and the road) where the older toms stay in the fenced pasture where we want them all to hang out. I thought about putting them all in a horse trailer for a few days to see if that would help but I am not sure that's a great idea. -Cortney
