HELP!!!

[kcwall11]

I have a Silkie chick (20ish weeks) that has gotten ill. When i put her in the coop last night, she was fine. This morning she was unable to stand, but was attempting to move. I put her in isolation with food/water. I put Corid in the water just to be on the safe side. When I got home, she was as in the same place and didn’t look like she has eaten or pooped since this morning. This is the 4th chick that I have had that got sick like this and they all died overnight. She is lifting her head and seems to be alert. She tries to call out but nothing is coming out.

I treated them on July 4th for coccidiosis, try to keep the coop clean (it’s been raining none stop), and they free-range throughout the day. I went ahead and treated the others for coccidiosis again today.

Have you any evidence they had coccidiosis?
Since you have lost 4 birds to the same condition, my advice is to send this bird to your state poultry lab for a humane euthanasia and necropsy. That is the only way to know for sure what you are dealing with. This will give you a plan of attack so you don't lose more birds.
