About five weeks ago we bought six Americauna hen chicks from a local feed store. They have all been doing great but yesterday one started just huddling in the corner by itself. We brought her in and put her in a box with a heat lamp. She eats fine and is drinking by herself...I have spent three hours on here reading the posts and I am only up to page 20. She prefers to lie with one foot in front of her and one behind her. She is still very alert and seems healthy otherwise. I read the other posts about giving them vitamins and we will try that but does anyone have any idea what this might be?? We have other chickens but they have not come into contact with the bigger birds yet. Is this a sign of Mareks?
