Don't know if anyone is interested but bought a 2L hand sprayer (pump type - 30 pumps then press a button and off you go) from wilkos today, was £2.99, then was £1.49 now 75p. Think will be great for disinfecting coop as tend to get normal sprayer all over my hands for some reason and will provide a sort of continuous spray.
Mind you, bought 2, one for me and one for my daughter so perhaps not SUCH a bargain!!!
Anyway, hope this is of use to someone!!
