Food? No. You're not thinking straight.

Several hundred arrows and a couple of bows, they will break.
You'll get 2-3 shotted there with best armor and food anyways.

If you have a friend, have them bring a fully upgraded tower shield for the ruins to block while you keep arrowing your way forward.

If you see a purple seeker, just accept your death.

The glazed honey chicken is amazing food. I don't use the eggs much. The eggs are used for a stamina food but since the salad recipe is so easy for x3 at a time and salad is such a great stamina food i never use the eggs.

honestly i am a bit let down by chicken and eggs, not using them in my food rotation at all. having finished the mistlands, my food setup is:

1. meat platter (replacing wolf jerky)
2. blood pudding
3. lox meat pie

the honey glazed chicken is the same as meat platter, but meat platter uses seeker meat, hare meat, and lox meat, which are all easily renewable. chicken meat must be "grown," which is more micro and base space than just going out and killing the right mobs.

the problem with mushroom omelette is its only a 25 minute food, so it doesnt sync up with the 30 minute foods.

so, unless you dont want to use the meat platter, i would say chickens are pretty irrelevant. if you dont use meat platter, then i would favor chicken meat over eggs. 3 eggs to make 1 omelette isnt as good as 1 chicken to make 1 honey glazed chicken.
