We keep our birds on our allotment as cannot have them at home (in the house deeds, can't have a pig either!). Next door allotment also has chickens, the guy is also our neighbour and has let us have the allotment we are on free, so I can't say anything to him. But...his coop is absolutely crawling with mites and goodness knows what else. When he collects his eggs he has to shake his arm and brush them off repeatedly it is soo bad. Despite regularly using gold label louse powder every time I clean out the coop, and a few times on the birds, our beautiful ladies are now infested. It's not too bad at the moment, but I would really appreciate advice as to how often to powder, what to use, etc.
It's sad because the worst one is our lovely hypno chick, clucky, named by my 6 yr old ds. She follows you around begging to be cuddled and as soon as you pick her up she dozes off! It was my daily therapy to have a lovely cuddle, but I'm not so keen now she has 'visitors'!
