re: pasty butt
I read years ago that adding ACV (apple cider vinegar WITH THE MOTHER -- I get Braggs) to chicks' water helps them avoid recurrences of pasty butt. It seems to be brought on by stress, so shipping would make it more common. I put a tablespoon of ACV in my chickens water (per gallon) on a regular basis. It may not help, but "it couldn't hurt" and my vet says it helps them fight off parasites, too.
