I heard caramel is similar to a cinnamon, but has white basing on the feathers that end in red. I normally either keep a pair, male and female, or bachelor pads of all males, barring a few troublemakers who are separated into their own enclosures due to picking and fighting, even in a larger pen... I guess those ones are just jerks.
Though in that pen with the 3 females and one male, I wanted more cinnamons and so I lumped them all together with the silver tux hen in there too just in-case the cinnamon male carried the tux gene also... The females all got along, but were unsure of the young male cinnamon I plopped in at first, but now flock to him when he tidbits.
