Hi, My 4 month old silky has had "bubbly" breathing for a few days now and as we have had very cold wet weather here, I thought that she could have a bit of a cold and was not too concerned about her. Keeping the pens dry has been a major problem too. However, yesterday I found her sitting in the pen,she seemed unwilling tomove, and I noticed when she did that her legs seemed very stiff. I seperated her, and today she is hardly walking, and her toes seem sort of bent,the bubling is worse and she has green diarohea. Could this be Mareks? She had an appetite yesterday,but today has not touched any of her food,and just sits on the bottom of the cage I have put her in. She makes honking noises when she sees me sounding like a goose with a bad cold - sorry,but that's the only way I can describe it. Is there anything else besides Mareks that can cause these symptoms. I run about 40 chickens here, and have worked hard on my little flock. I have not vaccinated as I believe in Natural remedies and lifestyle. But now I am really scared and worried for my chickens.
