Q.T. I'm predjudiced, but I'd recommend the Dominique. Rose comb not as prone to frost bite. Chicks easy to sex at hatch. They are an excellent forager, posess a nice demeanor, reported to be a good winter layer, and tasty meat bird, though not as large as a lot of other DP, but are more feed thrifty. Solid (not white) roo over Dom hen yields sex-linked chicks with a dominant rose comb. Doms will brood, though they're not habitual brooders. Otherwise, I'm partial to rose or pea combs, due to the nasty winters we get. And, my personal predjudice is for clean footed breeds. Here's a breed that's headed to extinction: Light or Dark Brown Rose Comb Leghorn. Nice large white egg from a smallish feed thrifty bird, excellent forager, good flyer, not as likely to be predator snacks. The only down side that I can see is that these birds tend to be a bit more flighty... which is the very reason that they are better equipped to evade predators.
My assisted chick has spraddle leg and a toe that is partial to curling on the left. She's otherwise doing well. I'll be researching splinting and making a bootie for her. That could be entirely due to the position she was stuck in when I assisted her out of the egg and put her back, figuring that she was a lost cause. She came from one of the smaller eggs, and her down is not well developed. That doesn't concern me, b/c the BSL from last year's hatch, though the first one to hatch, looked absolutely pathetic, and had short stubby down over the lower quadrant on one side of her body. (looked like a porcupine) She's my best layer, and people who see my chickens, comment on the "beautiful black one".
Final count: 20 live chicks, 2 required assist. 2 blood rings, 1 early quitter from a repaired cracked egg. 5 eggs left in incubator, 2 appear to be death prior to lock down, 3 DIS. Not excellent stats, but not too shabby either. Some of the chicks are small, obviously from small eggs. EE x RIR made a good showing of large nice looking chicks. They appear to be sexable, if only I knew the genetics I was looking at. (half of them are yellow, with minimal black broken striping on their backs, and the other half are more reddish brown with more of a chipmunk striping.) Most of the eggs that didn't hatch were disproportionately large.
