Now I didn't read all the postings , buuuuttttttt.
I have 8 or 9 in the coop and none crow at night that I know of. I've had chickens for a while. Most of these are Dels with one Amer. I had a CM roo and I don't recall him crowing at night either.
I have a Bantam brwn leghorn and he starts at 4:30 or later. Never had that. I figure breed makes the difference.
Now for DH, I would try to get the rooster back if you can. Buy or trade if you must but your relationship is more important than anything else. As long as DH understands the crowing might cause problems and he'll have to deal with it.
Hope this works out.
