RIR pullet 3 1/2 weeks old still has pasty butt, worried!

[HomeGrownChick]

My favorite little chick is Rhodie who has had pasty butt since I first brought her home. I have 7 chicks of various breeds in the flock, they all appear healthy except for my Dark Rhode Island Red's pasty butt problem. I have changed feed from medicated Purina to NatureSmart Organic (both "chick starter") with no change in the problem. She moves around the brooder comfortably, no apparent warmth/coolness problem. I keep the brooder clean, change the water & clean the bottle daily, same with the feeder. Is this just a normal situation she'll outgrow or is it an indicator of something else? Am I just "mother henning" her too much? Help?
Oh, also, her vent isn't clogged and I removed the pasty stuff under warm water. Her little behind is a bit bare of feathers from all of this!

Try putting some apple cider vinegar in their water. About 1/2 teaspoon per quart. Get the raw, unpasteurized kind such as Bragg's, it works wonders for clearing up pasty butt. I would start there and see if you get any improvement.

X2 - except that I would use 1 teaspoon per quart or 1 Tablespoon per gallon. All my batches of chicks that I've used this with either had their pasty butt cleared up or never had it.

Thank you so much! I'll try that right now, have Bragg's apple cider vinegar on hand at all times. I REALLY hope this fixes her up!
