I have sick birds. I am confused about what is wrong and which medication to give. Any help or advice would be appreciated. There are 6 birds. They are 12 weeks old and have been on medicated chick starter and pasture. I give them plain water and they also have mashed up hard boiled organic eggs and whatever bugs they find. They have been healthy and happy with no problems until yesterday morning. They are not at all overcrowded and I use pine shavings in their hen house and run. When I checked their house yesterday morning there was blood all over the bedding under the roosts. One of my EEs was looking lethargic and ill, not her usual rowdy self and at least two of my birds were having blood and mucous in their poo. I went to the feed store and was told they thought it was worms but all they had was piperzine so I gave them a 24 hour dose of D-Worm (piperzine) in their water. I also gave them yogurt to settle their tummies which all of them ate except Stevie, the very sick EE. She just laid around and occasionally got up and walked around slowly, drank some water and laid back down off by herself. She is perching though, which is a good sign yes? This morning there was even more blood everywhere and now both the EEs are moving very slow and seem ill. Stevie does not seem better and now she hiding in the hen house. The rest of the birds are not as peppy as usual. Neither of the EEs ate anything. They were drinking water yesterday and did get the worming meds but I am not sure how much. This morning we drove all the way out about 40 miles to the large feed store for advice. The woman there did not seem to know what it was nor did she ask any questions. She just gave me Neomycin (whoa) and I noticed they had Corid there so I grabbed that too. Neomycin seems harsh but not sure if it's cocci. Would worms cause this bloody poo symptom? I have no idea which meds to give or what they have. I love these chooks and do not want to poison them. Here are pics what I found in the hen house. I think at least half of the birds now are pooping like this. Watery projectile mucousy and bloody. The two birds who are ill are the EEs in my user pic when they were babies. They are my favorite birds.
