Went out this evening to check on my chickens (will be 2 yo in Sept) Found one sitting near the waterer, noticed she had a very pale comb and seemed to have trouble standing. The other 10 hens seem fine. She just sits there. I went to get a cage to isolate her and she had diarreha( very watery yellow with some white) I was out today so I have no idea if anything happened to her.I put her in the coop in a cage with food and water(not sure if she is eating and drinking) I gave antibiotic in water. Any ideas on what it could be?? I don't know if she laid an egg today or not. She is a Delaware. I plan to soak her in a warm bath in the morning. Could she be egg bound?? Do I need to give her yogurt? Any advice is appreciated! thanks!
