scaly legs

We have asked to be included in the next batch of Norwich based battery rescue hen adoptions. This means we will receive for a nominal sum a bunch of featherless, psychotic and claustrophobic chickens on the 19th of April. I had noticed one of our own was looking a little crusty around the legs and on closer inspection the scales were showing all the signs of scaly leg - a common complaint in poultry caused by mites which burrow under the scales leading to infections. The treatment is to use vaseline regularly on the legs until the scales drop off and new ones grow. I'll also need to disinfect the chicken house. This was an interesting 30 minute activity this evening! It would seem a little inept to introduce our new arrivals into an infected run.
