Katie, I've got 30 hens and at this time of year, I'm lucky if I get 2 eggs a week!! The cold, wet weather puts them off laying, as does the moult. Providing yours aren't too old (must admit, mine are getting on a bit!!), they should come back into lay in a few weeks, once they've moulted and the weather dries up a bit. It's a bit late for them to be moulting now, though - it's usually late autumn. Have you wormed them? If not, get some Flubenvet from your feed suppliers and do them while they're not laying, as you can't eat any eggs they lay whilst they're being dosed with it. Good luck! K x
