I have 32 chickens a mix. Rhode island reds, sexlincs, We have had chickens before and this year we decided to do it again. I live in the NorthEastern Pa and its getting down to about 30-40 every night now. I have 2 chicken coops both are 4X8. Since the weather has changed from summer my chickens have decided to stop laying. I guess I have to put up lights in the coops. I feed layer mash, scratch grain, and oyster shells. I am looking into solar lights for the coops.
