Feed cost for 2 - 4 chickens will be relatively small since a 50 lb bag will last quite a while. I use pine shavings, and I use about 1 50 lb bag/month.

Then, they switched them to a low fat (24% fat) or one of two moderate fat diets (34% fat) for five weeks. One of the moderate fat diets contained healthy fats like sunflower and canola oil; the other got the majority of its fat from one whole avocado per day.
1 This can take a week, even two, depending on temp and how hard the avocado was when you got it.  To expedite: Place several avocados in a paper bag and store at room temperature. The fruit emits ethylene gas as it ripens, and the bag captures the gas so it surrounds the fruit effectively. This might take 3-6 days.
