I've owned several breeds and found many "personalities" cross the board - from friendly to moody to down right nasty. But I've also had a few from an incubator that seem to "imprint" and have been very friendly initially , yet when introduce to the flock they can be "corrupted". They are "individuals" and as such will go their own way. Right now I have exclusively Sussex and found them to be quite friendly , though not necessarily all like to be held. But for a chicken that will come right up to greet you and eat out of your hand , all in my flock do.
