It can be the wrong temperature in the brooder or the feed. My hatch in December was on an Organic feed and I had a lot of pasty butt troubles. The hatches this year have been on Kalmback start right and maybe 3 pasty butts total. Making the feed into a mash can help too, make sure they are getting enough fluids and vitamins and that the brooder isn't too hot.
The chick's are on chick starter and I have been giving them vitamin / probiotics in their water. I'll check the heat. I took the Thermostat out to clean it, need to put it back in. Thanks
I've wondered if there is a correlation between the probiotics and pasty butt, haven't tested the theory though. It was just a thought with the last hatch when I had just a few. Maybe it changes the consistency just a little to where it sticks? Totally unproven
So darned adorable!!25 hatched and vaccinated! Only 2 eggs didn't hatch, one Ermine and one Fizzy. Surprisingly the silkie that I thought looked funky at lockdown, hatched a perfect little fluff ball!
Here are a few highlights!

We hatched 12 Fizzy chicks, 8 black and 4 blue.
I had one batch last summer with pasty butt issues so gave them Hydro-Hen (probiotics/electrolytes) and that cleared it up or coincidence did. Since then, I've always gave that in their water on Day 2 and again on Day 4 or 5. I'll get one pasty butt once in a while but it's rather rare.I've wondered if there is a correlation between the probiotics and pasty butt, haven't tested the theory though.

Whatever it is, I hope they grow out of the pasty butt stage quickly for you!
Of the 58 chicks in the last hatch, only 3 had an issue total, I did probiotics every other day for the first two weeks. Probably not related at all. I know that hatch I was using the organic feed, I had 2 or 3 a day I was cleaning up out of 10 total chicks for about a week.
and they are still wild 
or maybe they're just afraid I'll be giving them a dunk again 
Ok so can we conclude that it could be the probiotics? And maybe I should cut back to every other day? I made mash for the chick's because she was packed I noticed yesterday that Thelma was having issues with her behind and when I get back home she will be getting a warm bath. I put probiotics/ vitamin in their water because I have well water and they can't free range. Also, I'm picking up 25 Braham eggs this afternoonOf the 58 chicks in the last hatch, only 3 had an issue total, I did probiotics every other day for the first two weeks. Probably not related at all.
