Try to find a local source of properly cured/smoked slab bacon. This stuff will be fine un-refrigerated for a 10-day long trip. Also, un-washed eggs need no refrigeration for safe storage for a good while (especially if laid from salmonella-vaccinated hens).
While it may be a pain to haul eggs and bacon up a mountain...that breakfast on a fire in camp would be well worth it to me. I'd probably grab some bars/fruit for pre-dawn hunt-snacking and plan on coming back for proper breakfast mid-morning.
Also, I really enjoy pan-fried Spam...fat/protein rich, and salty with a bit of sugar to help keep your neurons firing. I also tend to bring along lots of cured meats; jerky, pepperoni and dried salami are stable for a a year in the pantry.
Another trick is to use your pack, sleeping bags, or insulated clothing as a make-shift temporary cooler. Take some breakfast sausage or pre-cooked casseroles, or anything you can freeze....vacuum seal two days worth of food in several smaller serving-size packs, and then freeze them so they are flat-ish....then right before you head out....pack your pre-chilled sorta-spoil-ey stuff like eggs and bacon in between the frozen things (in a garbage bag or two so the moisture stays in there), then pack in such a way around the meals, so they stay insulated in you pack by the clothing or sleeping bag. The frozen stuff can get eaten up in the first day or two, and will help cool and extend the other stuff's stability.
I really like the casseroles and other "freezer meals" vac-sealed for dinners, because they are as easy as boiling the bag in a pot of water and eating...no prep, less dishes...and you got hot water for any clean up or "showering" needs at the end of the day....try soaking your tired achy feet in hot water while you eat a hot, home-cooked meal, all by a fire out in the wilderness! Heaven on Earth!
