Partially overlapping with Tinker's post that appeared while I wrote this one:
It is intended behavior (but it's not particularly liked): you have to manually cut the cord first to get a piece that's only of the desired length.
You need decent tools and decent skills to be able to make decent staves, and new characters typically won't be able to meet those prerequisites.
My characters take quite some time before they trade, with the first trade often being meat from a larger kill (you can't eat that much before it spoils, and you can't smoke it without a sauna). Later on I trade hides for tools to gradually build up a set of tools, with a knife of any kind except stone being the first one, an axe of any kind except stone being the second one, followed by whatever missing tools I can find, with a particular emphasis on a broad knife (very important for hide working). After that the trading emphasis is on getting better quality tools (again, a masterwork broad knife is on the top of the list, but they also require quite a few hides).
Traps need bait to be reasonably effective, and 15 traps isn't that many. However, you're not really in a hurry to perform the game course tasks: just live the life normally and most of them will be met naturally as part of that. However, getting some food is fairly important, so it's a bit frustrating not to be able to catch anything.
Some times of the year see less bird activity than others, so you can go without any catch for quite some time if you're unlucky. Squirrels are good in that they're easy to catch once you've spotted one, and although they provide very little meat, their furs do have some value (you'll still need a fair number of them to be able to buy any tools).
