4 Chickens with white liquid poop!!

[momof12]

I have 4 chickens that have white runny poop. yesterday I went out and one of our layers had died, and i noticed that 4 of the other layers had white runny poop. i had been out to see the girls for a week, helping my son move and my daughter was feeding them. they are not suffereing from any respiratory symptoms, no change in food, washed their vents today a couple are matted, very red and oozing white liquid, gave them apple cider vinegar and garlic. any one have any ideas?

Can you start them on some Corid? You can buy it at Tractor Supply.

I do have some but I thought coccidosis was a young chicks problem and that it lead to bloody stools ?
