Just an update:
All remaining 6 are still with us. The healthy 3 still look good. The Olive Egger who is the sickest one left is not looking good. I think she won’t make it through the night, but I said that last night too. She hasn’t eaten today and I could only get a little Corid water down.
The other sick 2 don’t really seem sick to me. I’m still trying to figure out it whatever is going on with them is related or something else. I haven’t seen the Flower Hen do the weird neck think today and she is very lively so I’m hoping for the best with her. The Wyandotte seemed to be walking better yesterday but she’s totally uncoordinated and can’t walk again today, yet seems generally perky. Eating and drinking. I am so confused what is up with her.
Thanks to all who have helped with advice.
