We had 3 hens last May given to us by friend after buying poultry house previous December. One hen died from prolapse, one got bitten in head by dog but we nursed her back to life, and the other consistently laid soft shelled eggs. We had the most horrendous recurring red mite attacks, lice and no eggs from September through to this week. I spent a fortune on Smite, diatomaceous earth, poultry disinfectant, cider vinegar, VermX, poultry spice, grit, layers pellets etc. No eggs and nothing but trouble. Last week we gave up and sold hen house and my friend rehoused the 2 with her 20 on Monday. I have been round twice and my 2 are hiding in the big shed all day and if they come out are attacked by the other birds. They have undoubtedly lost weight and come running out when I call them. Ours were pets I suppose and they have joined a group that are tough 'street wise' birds who have to fight for food whereas ours were spoilt. I am a country girl and used to plucking pheasants, breeding pheasants for a shoot, skinning rabbits etc and aware that they are just animals. I was really upset however, and have told her we will have them back if things don't change by Monday. I cannot cope with another summer of red mites - I spent most weekends power washing hen house down and treating with dettol, diatom earth / Sprite but the mites continued and the hens were very unhappy. My husband will build us a new hen house but how can we stop the dreaded mites. Finances are a bit tight so really it needs to be home made and I have been told that plastic or metal will deter the mites. We live in the country and our garden is surrounded by hedges / wild birds and we cannot site the hen house away from a hedge - I believe this makes matters worse for mites. Help please...............
