Sorry I didn't check the updates until now. It's expensive for me because I am feeding them expensive organic food, although I just did a one ton order and sold over half of it so that helps out a bit but having control of their diet was my motivation for getting chickens so the cost isn't my issue, chickens can be kept pretty cheaply, too. We live in a housing track with 1/2 acre lots & I talked to most of the neighbors who would hear them and everyone was happy we were getting chickens but I don't think you buy into this area without expecting some livestock noise. 2 of my girls are rehomes from someone living in a Menifee housing tract where they were too noisy for the neighbors, one light brahma, one silkie. I also saw a light brahma & a marans on Craigslist for the same reason, too noisy so keep that in mind when picking breeds. My orpingtons have never said anything that I have heard, nor my australorp or bantam cochin. My easter eggers arean't really noisy either. The barred rock is somewhat vocal but nobody is like that light brahma, she has a 5 minutes thing she does at different times that is horrid and not even associated with laying an egg or anything, I haven't figured out the purpose yet.
I have to say I have been having a high stress commitment month and the most peaceful stress free feeling I get is when I am out about 6 in the evening with the breeze & the shade & the setting sun & the chickens, I have lots of other animals but there is something about them that is destressing. Just an FYI to help with your decision.
