Hello all just an intro, I am Steve and English my wife Dorota, is Polish but had lived in England for 30 years, we moved to Eastern Poland 5 years ago to retire to a small farm and have kept chickens for about a year and a half. 2 winters..... the last of which went down to -38 Celcius, I built a double walled, insulated chicken coop so we have had no problems with frostbite. In future I will encourage my wife to communicate...the chickens are really her project. We have some 25 Hens and a Cock or rather we had a cock.....the chickens range from two new hens (we think one is a cock because he/it tries to mount the other hens whereas her sister does not) 2 were hatched from a clutch of five under a broody hen. These two would be 5 months old now. Our problems have not been great, we have lost 4 hens to the local scourge (Not foxes - we have two large German Shepherds which keep any foxes well away (or dead in the case of two interlopers) But we do have 'kuna' (Central European Pine Marten which are slim enough to get through our doubled up deer fences ....The dogs have killed one so far......the others grabbed hens and half pulled them through the fence and chewed the bits they could reach through the fence) and of course large Eagle sized Red Buzzards which have taken one hen.....(speculation...the half eaten Hen body was on the ground in a brake of thin silver birch trees on fresh snow with no tracks leading to or from the body) Day before yesterday we noticed that our Cockerell (no idea how old he was, but he was a clean healthy bird with bright red feathers and a green tail, proud red comb and wattles he still had his spurs even...he was given to us last year because he was in a hen house with another cock and kept getting into fights with the other younger cock). Well he was on the perch standing tall but his comb seemed brighter than ever, his neck feathers seemed wet as did his comb and whole head, as if he were sweating profusely, there was some blood on one claw and splashes of blood all over the hen house as if a big fight had gone on, but we heard no noise, we normally would, but no other hen or the lone turkey we have showed any signs of blood on them...or distress of any kind, by yesterday he was down on the perch and still all wet about the head and shoulder feathers......this morning he was on the floor on his side......I put him in one of the nesting boxes but by this afternoon he had fallen from the box....still warm but lifeless. No other hen shows any signs of illness. Is this something that may affect my wife's whole flock? They are giving about 15 eggs a day......every day...all are well fed and look very healthy, they are all hardy birds bred here in eastern Poland. I hope to contribute and am happy to answer any questions that any of you might ask of me....or rather I hope my wife will contribute also.
