What causes pasty butt in chickens?

The pasty butt problem is caused by a few common issues, which you will read below. This issue is seen mostly in 1 to 2 week old chick.

Adult hens and roosters are not usually seen with pasty butt problem, but if they have serious health issues, you may see it.

Excessive Cold

Pasting may be caused by excessive cold temperatures. Freezing colds cause indigestion and diarrhea in newly hatched chicks.

The primary cause of this pasty butt in cold areas is a lack of proper brooding. Keeping the chicken coop warm in cold weather is crucial for chicken survival.

Use some suitable quality heat lamps and poultry heaters so that your chicks live comfortably and healthily. 

Excessive Heat

The most common cause of pasty butt in baby chick is overheating. If you are feeding baby chicks correctly, you need to keep an eye on their brooder with temperature control.

If the temperature is not controlled properly, the brooder guard may get too hot, which may cause pasting in chicks vents.

Read our guide on best heat lamps, where we have also provided the correct temperature chart for brooding baby chicks.

Sometimes excessive heat is caused because of hot climate areas. This overheating causes diarrhea and sticky poop, which leads to pasty butt.

In this condition, use good vitamins and electrolytes to help your baby chicks recover from the ongoing stress.

Bad Quality Feed

Feeding good quality poultry feed is most important in backyard farming. Proper feeding techniques have a crucial role in providing good gut health for chickens.

Baby chicks need pre-starter in the early weeks, but few new raisers give finish feed. This may be why chicks have indigestion, which may lead to pasty butt in its chronic phase.

This causes diarrhea and various intestinal issues, which is the primary cause of pasty vent. So, always provide a good quality poultry feed to your little ones.

Don’t be confused between the chicken treats and daily feed. Feed is given daily, and treats are occasionally.

Dehydrated Chicks

The majority of the chicken raisers buy from far hatcheries. We always order clicks from big hatcheries, but they are about 200 miles away from our poultry farm.

The reason behind ordering from so far is only good quality chicks and pure breed.

Giving too many vitamins and electrolytes to dehydrated chicks can make their butts stick to their feathers. 

Always give your dehydrated chicks clean cold water for a few hours, and then give them electrolytes. If the room temperature is normal, do not switch on the brooder for a few hours.

Parasite infestation

In certain conditions, you may see pasting in chickens because of parasitic infections. A worm infestation in chickens reduces intestinal nutrients absorption, which leads to sticky droppings.

Pasting because of worm infestation is mainly seen in adult chickens. So, keep your poultry feed and litter clean, which avoids these types of health issues.
