Hi, I am looking for opinions/experiences. We got our first chickens last June and had a flock of five (started with six, but one was a roo who got re-homed). This weekend a fox got two of our girls. We have a spacious coop and run (built for six girls) and are contemplating adding two or three to our flock. I've been reading out bringing in new girls to a flock and am questioning if we should do it right away; be happy with three girls; or wait a until Spring of 2012 to stagger ages/laying. If we brought in new girls now they would be 4 - 6 months old (ours are 6 months old and not laying yet). I am a bit worried about the quarantine period. How have folks done that in a city yard? We have a big lot and can probably borrow a small coop and run from a neighbor who hasn't gotten her chickens yet. Though it has a small hardwire run, we won't be able to bury hardwire cloth around the temporary run/coop. I am worried about the predator proofing aspect, especially since the neighborhood fox(es) have figured out where a meal is. Our original flock was VERY happy and content. My other worry is about bringing in new girls and it not being a happy and content flock. What are people's experiences with adding to a small backyard flock. Thanks all!! Appreciate any experiences/input/advice/thought.
