DH was working in the garden & heard a commotion in the chicken run across the yard. The cockerel appeared to be paying his attentions to one of the white chickens. I checked the chickens and saw no broken feathers but the two most mature white rock pullets had dirty backs. We have 2 or 3 pullets with red combs and wattles. Does this mean I have an exceptionally horny cockerelor point of lay pullets? These are my first chickens. The cockerel and RIR pullets are 17 weeks and the White Rock pullets are 16 weeks.
