Hello,
interesting, even if weird sounding question on a forum about chickens.
To get the best price for animals that otherwise end up killed anyway, you need to find a hatchery in your area that does egg-laying hens.
When the chicks are born, they sex them and just keep the females, to grow into egg-laying hens.
The males, called in French"coq-frères" ( brother chicks?) (Yep, I am from that French speaking part of North America) are routinely sold to people raising birds of prey, who use them as food for their falcons, etc.
You can also buy these day-old chicks, but the producer will want to sell you these by the humdreds, if not by the thousand.
You really want to buy the males, as they are usually priced at 5¢ each. The females are sold at around 1.00$ each.
Flesh chickens are not a deal either, because both sexes are used by the industry, and are thus sold at 1.00$ each.
The industry has no use for the males of egg-layers breeds, because they don't fleshup quick enough. They are considered waste.
Besides a few Italians who know their food and will rise them for chicken instead of our overquick-growing, soft fleshed, insipid barbecue chicken, these birds have really no other use and would be killed anyway.
At least, you would be making use of this little life that would be shed anyway.
Now, the hatchery will probably charge you 3.00$ per box the chicks are in, as they are special boxes, and this almost doubles the price per hundred from the start. I wisely bring my own cardboard boxes.
If you want to buy them already frozen, you can go to Rodentpro, but you'll probably end up paying 25¢ per chick, plus shipping fees.
If you have other friends who own snakes or reptiles, you can even start a little business, or share with them. On Rodentpro, you will even get the nutritional values of different preys. Chicks are similar to mices in this aspect.
And snakes are like everybody else: they love chicken!
Two things, though: you have to kill them humanely, of course; and, most important: don't EVER show them alive to your kids or bring the chirping boxes in your home when the kids are there, if you have kids: you'll likely traumatize your kids or break their hearts, and have to dryso many heartbroken tears: baby chicks are really so cute!
Worse: don't EVER think of putting them to sleep in front of kids: they would resent you for life!
And I can't garantee you yourself won't feel sad afterwards.
The only thing I know is: it sure beats rising mices and rats and killing them (ugghhh...).
And these poor chicks would anyway end up dead, but go in the trash otherwise.
If you want to discuss this even more (ex.: quickest, most economical and humane way of dispatching them), just email me.
