Yes Herbs make all the difference when fed to the Chickens. The eggs have an amazing orange yoke and are awesome..... When we had Chickens before I always made sure to grow lots and dry them. I also use the herbs in the nest box, it makes the chickens nice and relaxed and want to go in and lay. Herbs have lots of healing powers as well. My Chickens in the past loved to eat the herbs just like treats.
My Cellar smells amazing as well as my kitchen which has lemon thyme in the dehydrator. Have Rosemary hanging in the half bathroom which is a delightful aroma.
