Soon, I am moving to Minnesota, and will be living with my grandma and going to the U of M! I can't bring my flock with me, but I want to start another. I checked out regulations. Unlimited chickens are allowed in the Minneapolis area(or just unspecified #), as long as 80% or your neighbors in a 100-foot radius agree that it is O.K. My concern is noise. Right now, I only have a handful of hens and no rooster, and I only occasionally hear little clucks. Its pretty quiet! However, I want to up this number to perhaps 25 hens. Would a flock of 25 hens be too loud? I would be living in a pretty quiet suburb, on perhaps a three-acre lot. Neighbors flank two sides of the property, nobody in the back, and a street to the front. What do you think is the largest amount of hens possible whilst keeping the noise to a minimum? Thank you!
