Howdy from another mama of 6 kiddos.
I've had hatchery buff orps, and they were my worst pickers. They were pretty cannibalistic, and everyone in the hen house was bald. They free ranged, so space was not an issue.
I've had hatchery RIR's, and only kept them for about 15 weeks. They were racist, and were picking on everyone else. As long as they were in the hen house, it was chaotic. Most everyone (besides the RIR's) was missing tail feathers. I'd see them run past another bird, and grab a random beak full of feathers. When I sold them, that behavior was gone and it's been peaceful since.
I love my hatchery BR's. They're calm, friendly, and have a lot of personality. My 9 and 10yo's claimed my two BR's as their personal pets, named them Barbara and Babs, and they adore them. They are very dependable layers as well.
I love my polish, but at 6 and 7 months old, I don't think I've had an egg from them yet. They're pretty, but I think I'll just keep these few as eye candy and not order any more.
I LOVE my golden-laced wyandotte. She's massive, beautiful, and laying pretty consistently. She's 6 months old, and my favorite of all my egg girls. She's not as friendly yet as the barred rocks, who are 4 months older than her, but I think the friendliness will come as she matures a bit.
I've also got one black australorp, who is consistently laying the darkest eggs in my coop. She's also 6 months, and she's beautiful the way she shines in the sunshine. I'm really growing very fond of her.
I've ALSO got some bantam cochins, and they're delightful. They're only 14 weeks old, and so they're not laying yet, but they're VERY calm and friendly. Their personality just might turn out to be my favorite. I would recommend them to any family who wants friendly, sweet birds. Their eggs will be small, but I didn't buy them for laying. I got them specifically to be broody, so I can rely on someone to keep us in chicks. I don't know if I can wait for them to grow up before I hatch, so I'm working on getting stuff together to build an incubator.
And I can't not mention my Easter eggers. I love getting their green eggs, and they're laying about every day. They're calm, and relatively shy. Every flock needs EE's.
I'm turning into a hopeless, chicken-addicted woman. Good thing my hubby loves me so much!
