You need to be careful when using a trough style feeder with meaties...they tend to eat and sleep in the same spot..they will pile into an empty feeder and sleep when young..those on the bottom of the pile do not do well..
My opinion is to ditch the high protein feed and the pasty butt will stop. But I am in the minority in my thinking on that......the healthiest birds I ever have, no matter what they are, is when they are broody raised, they eat what everyone else is eating in that case. And only get extra protein in the treats they are given.
if you are worried about cocci you could just add oregano and cinnamon to the feed. All my meaties start on this instead of medicated feed.
I've already noticed that they like to lay down a lot more than the heritage. A couple of them were just laying down in front of the feeder eating... Talk about lazy. I was thinking trough so that there was plenty of space for them to all eat at once so they didn't trample each other trying to find space at a bowl. What type of feeder do you like for meaties? Just have a couple of bowls so they can all find a spot?
I don't think my feed is medicated, I've been adding cayenne for cocci since I have turkeys in there too (also a big reason for the higher protein food). I took the pasty butt chicks back down to the brooder. I figure at this point stress is probably part of the problem and it's much less stressful downstairs away from kids and dogs. Only two of the birds still had crud on their butts and it didn't seem to obstruct their bowels at all, so I just cleaned them up and took them back down.
I do have some pictures to share once I get a chance to sit down at the computer... It's crazy how much bigger the cornish roasters are after just one week... They are nearly the size of the turkeys that are a whole week or two older!
