I'm in Ft Collins as well...well, that's the address although our back fence is the city line, so technically we're in the county. It took some serious research but I finally discovered that here, we're allowed up to 6 chickens, but no roosters. It was actually pretty easy to find info for the city but took more work for the county.
We picked up our girls yesterday, woohoo! Hubby has lots of chicken experience but when I took one to the cage it was the first time I'd ever touched a live bird...it was awesome! We got 6 red sexlinks that are about 8 months old and the woman we got them from said they started laying in May and hadn't missed a day since. One of the girls just popped one out, which surprised me...after the stress of the move and our dogs, I figured it would put 'em off for a day or two.
Anyway, hope this might help others...it's a reply I got from the county:
