Two weeks we combined our two small flocks into one large flock. It went very well. Last week we attached the two coops into one large coop, more floor space. We removed the roosts from one side and added more to the other side. Roosts are now at one end and nesting boxes at the other. Three of the four hens who lived in the coop with the nesting boxes have now taken to roosting in the nesting boxes at night instead of moving to the roosts at the other end. The fourth hen has moved to the "new" part of the coop and are roosting with the other chickens. Is there anyway of getting the three hens out of the nesting boxes and onto the roosts with the other chickens? Winter and cold weather is coming to Upstate New York very quickly.
