Pasty butt is a common and potentially fatal condition in baby chicks where manure sticks to the down around their vent and hardens.
Pasty butt is not a disease, but rather a reaction to a chick's delicate system adjusting to a new environment.
Common triggers include:
-Stress, it can be especially common in chicks shipped from hatcheries.
-Temperature, the brooder being too hot or too cold.
-Diet, feeding chicks treats or snacks before they are fully grown. Ensure that you stick to a plain chick starter for the first several weeks.
This blockage stops waste from passing. It is easily treated by gently softening the blockage with warm water and wiping it away. Never pull or scrape the dried manure off, as this can tear the chick's sensitive and delicate skin around their vent.
Be sure to monitor your chick's backsides for the first several days for signs of pasty butt.
