Why does only one of my chicks have past butt?

[alexismaria]

Ok, so about 5 or 6 days ago we purchased pullet chicks from our local tractor supply and one of them now has pasty butt and I'm not sure if I should keep her (all are hens) away from the other chicks?? And how to get rid of pasty butt without cleaning the chick everyday, any easy solutions??

Pasty butt in its common form is a side effect of stress and nothing contagious. Some birds will have it and some will not.

The only treatment is daily cleaning, though trimming and removing most of the down around the vent reduces incidence significantly.
