We have a sick 16 week old Silver Laced Wyandot. She has a pale pink comb, drooping tale feathers, will drink and eat a little and stands and walks a bit but then just plops down. Her poo is almost white/yellowish and very runny. Any suggestions? We just started her on the mix with water for coccidiosis. She is separated from the other girls. Any suggestions would be greatly appreciated. She is a sweet girl. Thanks!
