I had 4 chickens and all were killed but one. Will it be relatively easy to introduce one or two back with her? I have read the different ways to do so and have a good idea of how to do this. I just wanted to find out if it is easier to introduce a new girl to just one instead of a flock. Also, does anyone have an opinion on number of chickens in a flock? Is 3 just as easy as 4? When I had 4 hens they often paired up in 2s when they free ranged. Is 3 an odd number that is likely to get one of them picked on more? Any thoughts are appreciated!
