Pleasure! Yeah, there does seem to be a lot more to it than that but it sounds like your chickens have about as wonderful a life as could be hoped! I think the Hatchery factor could be the part that is hardest to do anything about. If they were bred and raised to not move around as freely and naturally as your chicks get to enjoy, then all kinds of natural traits and behaviors get lost in place of higher returns on meat or eggs in shorter times. If they don't get to move or see much light, who is going to notice the beak? I've also heard of people's experiences rescuing cage birds and struggling with hens that have no instinct for scratching. And thus need to learn from established hens.
