Wash your hands, remove any rings and get ready to get messy.
Noodles: Break warmed eggs into a large bowl. Add 3/4 of the flour and mix with a wooden spoon until most of the flour is combined with the eggs. "Squish" dough through your fingers. Dough will probably be pretty sticky. Add a little more flour. Continue squishing through your fingers and kneading dough and adding small amounts of flour until dough is no longer sticky. You can add a little water if you get it too dry. The key here is to have the dough just to the point of not being sticky.
Let dough rest 20-30 min (allows gluten to develop).
Meanwhile, start broth and water boiling. Slice carrot, celery and onion and chop chicken. Add vegetables, chicken, garlic powder, onion powder and parsley to broth.
Take rested dough and run through your pasta machine to desired thickness and cut into 1/4" wide noodles (if you don't have one, that's OK -- skip to the next step!). Cut noodles to desired length. Separate noodles and lay out to dry until veggies are tender.
No pasta machine? Wipe down your counter and dry thoroughly. Dust a 1 foot circular area with all-purpose flour. Place rested dough on floured counter. Knead gently a few times. Re-flour counter and dough. Knead until pasta is smooth. Roll out with a rolling pin to 1/8" thick and cut into 1/4" thick strips with a sharp knife or pizza cutter(don't cut the counter). Cut to desired length. Separate noodles and lay out to dry until veggies are tender.
When veggies are tender, add noodles and allow to boil 3-5 minutes until tender.
Season with salt and pepper as desired.
Portions can be frozen for later, if desired.
