I've had them for about 20+ weeks & they are handreeared & have not seen other chickens outside of their little flock. I've read 2 cockerels to 4 pullets can be a big problem & am waiting to act if it becomes one. but one brown cockerel has only tried to mate three times a few weeks back, was rejected & didn't try again & the other grey cockerel tried a couple of times to & then resigned himself to abstinence. They are both excellent with the pullets & get along as well as boys can, just an occasional displaying tiff here & there. There is a pecking order that's long established with the grey barred protective cockerel at the top, then a pekin bantam pullet thats older than all the others, then the brown cockerel thats an utter coward, fat tony an EE, Naughty nugget another EE & some strange little black & brown bantam that we don't know what the hell it is. Non of the girls are laying yet, so non are receptive. I thought when the boys were ready, they would rape the girls, but its like a polite "Not tonight dear" indignant squawk or squeak from the pullets & the boys leave them be. They are both obviously ready to mate, but don't force the issue. I'm worried they will never start breeding, let alone overmate the pullets. They are both sweet, protective boys but.... Come on! They remind me of the boys in high school, twiddling there thumbs, too shy to ask the girls on a date! Right now I can see both boys cuddling all the pullets on the perch through the window. There is an order of pullet, cockerel, pullet, cockerel, pullet. Its kind of weird. The fourth pullet I'm using as a lap warmer because I'm cold. When are they going to start mating & laying? I've added a light just to kick start them into laying. Its set to turn on at dusk & off a 10pm, normal summertime. The idea is I'm going to remove it in the summer when the sun sets at 10pm & leave them on natural light after that. Also, one of my pullets perches bolt upright & looks like a parrot from here..... weird bird! Added: The smallest pullet has just wriggled under the brown cockerel & he's just sitting on her on the perch, covering her with feathers. I can just about see a tail... Its very cold here. She seems to have stuffed herself between his legs.
