Hello BroodyMama! How exciting to start on a new adventure! I drew out a rough idea for what your yard could become. If you are set on 2 coops, i would add the second one at the end of the yard, and run a fence splitting the proposed chicken yard in half. This plan gives you 4 beds measuring 20'x4', a 40'x20' chicken yard, room for an herb garden, rabbit hutch, small orchard, composting area, and recreation zone (I recommend Koob - very fun!)
Be sure when setting up the coops that you have access to their droppings underneath. Given enough composting time, chicken manure is a valuable resource to have in a garden. You can layer it in a garden bed really thick (right on top) mixed with old straw, and after winter is over you have the perfect bed for planting corn!
I put the chicken run in the one corner because it looks like there is a tree there. I currently have ducks (no chickens), but when I did have chickens they always preferred to be under the tree, rather than out in the open.
