Stropps, not sure on the chickens not laying, though as a general rule, the posher the chicken, the less it lays. So fancy breeds lay less than the bog standard hybrids..... Bit like schools, the more you pay, the less you get 
My five weren't laying, but they are three years old, so I figured they were just taking a rest. Also thought I might shock them into laying by introducing four new girls. They aren't rescue, but from the local agricultural suppliers, where you say what you want, a big burly man goes into a shed and comes out with armfuls of birds and puts them in the back of your car....very eventful last weekend!
Herbs, I think the singing thing loudly might work a la Kings Speech.
Mine is a narrator in the Xmas play and has one line - god knows how many narrators there are!
