I just received 15 chicks from Meyers that are now 4 days old. The first couple days they all thrived and still are but I'm noticing there beginning to get pasty butt. Not all of them have this and a couple others have it to what I think bad. Yesterday evening I trimmed up what I could, whipped them clean and put a small amount of olive oil on the ones that were bad. I'm not sure if there is much else I can do to prevent it from happining and I would like any feedback possible. I also added ACV to the water.
