Long ago a friend of mine said that back on the farm, they simply fed the chickens whatever feed the cows ate, but added cayenne pepper for egg stimulation. This is a very old trick, seems like! Well, a few years back, one of my old hens who did not lay anymore began stealing sips of coffee out of my cup in the morning - ugh, wasted my coffee! It had cream and sugar, so I guess she liked the taste. Then she began to lay again! Laid on and off, more on than off (except for moulting) for the next 5 yrs. (I kept giving her some of my coffee, so she wouldn't get it out of my cup) Died of old age and moult at 9 yrs. So I'm a believer in coffee, as well as pepper. Now I have hens that are one year old, who don't need the stimulation yet, but I'm surely going to give them coffee when they slack off.
