Ant advise would be appreciated. I was given 5 hens by a friend as she was emigrating to Canada in November 2011. They have all been pretty healthy apart from mites which i cured right away. 2 weeks ago the eggs became a little few and far between but as there were lots of feathers on the ground i put it down to moulting. Last week 1 hen`s tail was pointing to the ground instead of up in the air, she did not run out in the mornings but just strolled out last and was in no hurry like she normally was. She looks tired but is eating and drinking. Sje seems to spend her time alone almost like she wants some peace. Today i have just been out to let them all into the garden and another one has a tail pointing down and as she walks she looks like she is drunk and staggering. All eyes are clean no no muck from any end. No signs of mites or lice... i am baffled!!!
