As someone who has kept free range hens (for eggs) for many a year, I think I am qualified to comment.
Chances are, the yolk colour that you get off young Garry is due to an additive in the feed the hens are eating. The fashion these days is for very dark shells and very dark yolks (in contrast with much of the world), and additives (natural or artificial) can be put into the hen feed to alter these.
In terms on animal welfare, I don't think it's as clear cut as saying one is better than the other. If anyone has ever experienced how stupid hens are, you'll know it's unlikely that they experience any kind of happiness, but you can certainly tell when they're not feeling too great for whatever reason.
Free range is all very well, but it does come with disadvantages. Most hens would prefer to be inside on a cold, wet January day, but will not have the brains to do anything except shelter under a bush, shiver and get dripped on. Also:
* They will (or should) also be fed on a dietary supplement of grass pellets or similar.
* They will also be at the mercy of predators, such as foxes. This causes them a lot of stress, particularly when foxy comes and helps himself to a chicken drumstick or two (and nothing else), leaving limbless, squawking hens bleeding to death. Such is Nature's way.
However:
* They will get to enjoy the glorious sunshine (when it's out), giving the originally sub-tropical birds a more natural lifestyle.
* They will not overheat indoors during the day.
* They will get more exercise, and increase muscle:fat ratio.
* They will eat a more natural, omnivorous diet, including field mice, frogs, etc.
So there are points either way. In reality, in many free range systems, many hens never get outside for reasonable periods of time, and when they do, it is into a bare earthen yard. While this is not necessarily bad for them, it makes "free range" a bit of misnomer. Ours had 22 acres of boggy scrub to root around in, surrounded by Forestry Commission land, and I'm not sure that was any better.
In my opinion, there is no real ethical difference between "barn" and "free range" hens or eggs, given my experience. Thankfully, cages as we knew them have now in all essence been made illegal, as I don't believe this did the hens any good. The actual quality of eggs depends more on how strict the egg graders are than what the hens are like. Also bear in mind that it is in the farmer's interest to keep the hens happy: unhappy hens won't put on weight or lay eggs.
In terms of age, you can compare it to other animals: hens live for about 3-4 years and reach puberty at about 10-14 weeks (i.e. that's when their voices drop and they start laying). Carcass size is generally proportional to age. Compare that to your roast lamb and make your own judgements.
