Well this won't answer all of your questions, but here are a few of my numbers.
Purchased chicks for $2/piece
They are now 10 weeks old I have 44 of them, 6 are banty's and we have gone through 250lbs of food, at $15/50lbs so that would so far total $163 That is $3.70 per chick so far, I have at lest 7-10 more weeks to feed them before they even start laying, and they seem to eat more, every single day, I wish I had a run for them right now, but I don't so it is all bought feed.
I estimate I wil go through another 250lbs of food before they lay, so another $75 in feed.
Hope that helps you figure out costs.
On a different spectrum, I bought hens that were already laying 8 of them for $55, 2 dies so I have 6 and I am getting an average of 2 eggs/day that isn't even enough to feed my family all that we want to eat yet, so I haven't sold any of them yet. I have bought 100lbs of food for them, and we probably have 25lbs left, maybe even 30lbs, they free range most days. So it has cost around $80 so far to buy and feed the hens and they have given us approx. 140 eggs, that doesn't even seem possible, but yeah so the eggs have so far cost $6.90/doz LOL that should go down considerably when I am getting a better % of them laying, 2 days this week I had 3 eggs each, now today I got 1.
Now if that isn't confusing chicken math for you, I'm not sure what is.
Just wait till the chicks start laying and see how much those eggs cost me
