Thanks for all your help, we have got red mite, found evidence of the little bliters in house, chicken have lice too! This parasite job never ends thought it was bad enough with the sheep. Anyway also bought hens new much higher up house as well cause we thought old one too close to ground,these are very spoilt hens. going to have a blitz on anything creepy and wiggling today,so keep moving hubby or you'll get done too.
