I spend enough time with my girls to notice weight differences when I pick them up and cuddle them, and I have noticed a weight drop in my speckled sussex, I.Q. Shes not emaciated but I feel a difference. I have not observed worms in her poo or seen mites and she is the only one with this problem. She acts totally normal and eats like a pig. She is just about 5 months, not laying yet. Ideas?
