newbie: how can i get them to eat?

mine wouldn't touch one make of pellets, they condescend to eat another make (farmgate?) if I withold wheat. to feed fubenvet I dampen wheat, a, so it sticks to the wheat and b, the hens prefer wheat damp esp soaked then drained.
how about explaining to your neighbour that they may DIE if they don't eat their medicine, but they won't eat their medicine while they are being given treats instead, just ask her not to feed them for a week (10days for her benefit) while they are treated, then small quantities of treats, like a child, getting fat would be unhealthy.
