Tweedy seems to be getting a little bit better. I've increased the amounts of treats the chickens get (more sunflower seeds, and more mixed grains) so that if she needs extra energy right now, she gets it. Her limp yesterday looked really bad, but today it seems less painful, more mobile, and she looks more fluffy. Unhappy hens are not a fluffed up, while happy hens are fluffy and perky looking. Yesterday her feathers were definitely downcast, which concerns me.
I really hope she feels better soon. Poor girl.
Also, it has been wet here for a week or two, so the hen yard is a muddy, filthy mess. I really hope that isn't making her recovery more difficult. Her nails are pretty sharp so I doubt she is slipping in the mud, but still. It can't be making it any easier!
