I have 4 laying hybrids.
I must say my Buff Sussex in particular (buff orpingotn X Light Sussex) is absolutely gorgeous and very brave and intelligent, its much younger than the rest of my birds but is most often the first to do new things and does well to fight off the others for food.
I also have Black Rock, which is extremely healthy, hardy, virgorous and very chickeny (does all the fun behaviour like scratching, worm hunting, jumping, tearing/yanking, bathing in Soil etc. And it has beatiful solid back feathers.
In addition to these I got a bluebell (a grey, cautious and shy bird) and a Hyline Brown (commercial breed, practically impossible to hold, hates snow, grumpy/bully)
I like them all in their own ways, Hyline is my least favourite at the moment, but I expect it to regain my admiration by laying more eggs than the others.
