I noticed yesterday that one of our Silver Laced Wyandotte pullets (approx. 6 months old) went in the coop to roost early. She seemed a little lethargic, but I left her alone. This morning, she didn't come running out of the coop with all the other birds but stayed up on her roost. She eventually came out, but seemed a little unsteady on her feet and pretty lethargic. She was waaaay too easy to catch! I isolated her in a cage with water and layer pellets. I gave her a little kale which she snapped right up. I also gave her some plain yogurt with pellets mixed in. She ate the yogurt, but didn't touch the pellets. She's drinking water, but has green diarrhea. Her wattles and comb seem a little pale and dry, but her eyes are bright. What's up with her? Any help is much appreciated!!!
