I do wonder if their bones and joints and immunities will be as healthy as they don't run around in the sunshine as early, but they seem good so far. I'm curious to see if they lay sooner or what.
Structurally speaking, they're going to be fine. There will be no difference.
The advantages I can see for natural incubation: less money for electricity, less hands on care, ability to turn out on range earlier, extremely rare instance of cannibalism; disadvantages: much, much harder to hatch in number, if one hatches many broods, the care complicates quickly as well as the need for broody coops, random availability and the general capriciousness of individuality.
The advantages of artificial incubation: assuming respectable egg availability and fertility, much--much more control over dates and numbers, which leads to easier systematization. Increased numbers and predictable dates enable stock improvement. Disadvantages: more expensive energy-wise, slightly more care, but once you're old hat, not really a lot, increased probability of cannibalism, large numbers signify that one must very aware of floor-space needs and respond at the moment, or before the moment, of need lest cannibalism, etc. break out, longer wait for turning out on free-range.
As for the dual-purpose need for broodiness, first of all, it's not hard to select for broodiness. You're not going to do a lick of damage on that front by opting for artificial incubation. Natural tendency towards reproductivity is much more resilient than that.
