You should be aware that "wait and see at the TSC" is HIGHLY regional. This past two years, my local TSCs (multiple) have sold out of birds on delivery day on numerous occasions before I could make the 40 minute, or 1 hour, drive in to town - and they will neither "hold them" for you, or even allow you to pre-pay and pick up.
So while its good advice generally, your specific circumstances may differ.
Free on Craigslist is uncertain (quantity, condition) but a good way to introduce unknowns to your property. Granted, a quick culling helps mitigate. Just be aware that you are balancing cost and risk. If your only concern is cheap meat, that's an easy equation - but if you maintain a flock of your own which you value for breeding or show, probably not the best idea. If your flock is merely high turn over production layers for eggs??? Well, that's a more nuanced trade with wide disagreement between reasonable persons.
