You have quite a sizable farm and a big flock of chickens. We had around 3 dozen breeds (over 200 chickens total) and about a dozen ducks on a 39 acre farm once, so I know how much fun it is, and no matter how many chickens you have, you love them all. We currently have only 25 hens (4 different breeds). Good luck with your farm.I have about 60 of different breeds free ranging our 40 acre farm. Turkeys and geese too. Live them all
