I had a flock of 9 chickens-my first year- the chickens are 6 months old- last week the woman who watches them when I am not around left the coop open and 3 chickens were killed. I am devastated. Every time I see my chickens now it seems like there is an emptiness. I was thinking of getting 3 pullets in October but I am not sure if it is a good idea since the winter is coming- and I live in New York, Hudson Valley, where it can get cold. I would be ordering them from McMurray Hatchery. Any advice on whether this is a bad idea or not to do now.
