I haven't tried the cayenne pepper but mine stopped laying recently (I assumed it was because it started getting dark so early) so I put a fluorescent light in the coop on a timer to extend the day. Within a week they were back to laying 7 a day on average with 12 chickens that are less than a year old. The buff's seem to be laying the best but the Araucana quit laying completely. (I have two barred rocks and some "mutts" in there also.)
