Well, no real news on the "violating ordinance" front.  My real estate broker wants to see the letter I was given, and she asked me to drop it off at her house this weekend.  I'm picking up my mail this evening and if there is anything else, like the citation (the letter I have is a courtesy letter) the code enforcement officer warned would be sent, I'm gonna give that to her too.
This evening is the chicken gathering trip for the rest of the flock.  Well, minus the ducks, as I think those six need a special trip all their own.  Perhaps Sunday evening (I have Monday off).
The relocated flock members have been ranging freely for a few days.  Everybody, even Kate and Angus the geese go into the coop at night before the auto door closes.
A couple of nights ago, I took a carton of 18 eggs to the retired couple's house next door.  They're the closest to the coop and where most of the flock hangs out, so they are most impacted by rooster crow-feasts. Two other neighbors were present on their deck with them, the "suspect" neighbor and one of the owners of property adjacent to and "behind" mine.  The driveway up to the house is VERY steep, and I was huffing and puffing when I got up there with my gift of colorful eggs. 
They pulled out a chair for me and the lady off the house brought me a large glass of iced water (I turned down the offer of an alcoholic beverage).  We spent a good 30 minutes or so, just chatting about my chickens.  I did not tip to having ANY problems or mention code enforcement at all.  Yes, the retired couple had been bothered by the roosters the first couple of nights, but "it's not been so bad the last two days.". The neighbor from behind my property interjected, "Oh, it's early yet, they're getting used to where they live.  You won't even notice them in a couple of months, trust me.  You'll get used to them and sleep through it.  Honest." 
That was nice of him to say.  He also said he would get my number later, as he'd buy a dozen eggs a week from me.
The "suspect," visiting neighbor indicated his grandmother had chickens, and a "mean rooster" his grandfather hot when it attacked her.  He also said the roosters would get louder this weekend, because the moon is full on Saturday.
Oh, really?  Hmmm.  I was asked if the roosters were kept in the coop at night; yes.  They all said the black one was gorgeous.  I told them that was Bartholomew, and all the chickens have names. I explained that one bantam Cochin rooster was being a real jerk right now, picking on other roosters in the re-ordering of the pecking order.  Carl, Bart, Frick, and the geese kick his butt, but the others are being mercilessly chaes and attacked.
You have three roosters, right?
"No, I have eight.  I want to be a good neighbor, so PLEASE let me know if it's too much to deal with after a while."
Mrs. Retiree said she would give it a little longer, but she really appreciated my saying that.
We parted on pleasant terms (she insisted I take the glass of water with me and return the glass some other time) as HHandbasket
arrived for a shopping excursion and everybody said good-bye, with the Behind Me neighbor reminding me he wanted a dozen eggs a week.  You betcha!
I think it was clever of me not to mention anything about the complaint, although the "Carls" know about it and are upset on my behalf.
On another note, I had a gang of five young chickens come around the house and through the open French doord to nap on a rug just inside the doorway.  I'd have taken a picture if they hadn't scattered and run outside when I discovered them.
I have NOT moved my furniture or goods up here yet, just a few things here and there and what I need to wear to work and on the weekends this time of year.  Once I have all the fowl in residence, I can stop worrying about them living at the rental property and focus on what I need to do to move what I do want to fill the house.  Then what should be donated to the Goodwill, and what needs to be thrown in the trash.  THEN break down the ponds, the coop compound, etc.
