What causes pasty butt in chickens?

The pasty butt problem is caused by a few common issues, which you will read below. You see this issue primarily in 1 to 2 week old chicks.

This pasting poop problem is rarely seen in adult hens and roosters, but you may see this issue if they have serious health issues.

Excessive Cold

Pasting may be caused by excessive cold temperatures. Freezing colds cause indigestion and diarrhoea 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

Overheating is the most common issue which causes pasty butt in baby chicks. If you are still giving a proper feed, you face this issue, then use a good brooder with temperature control.

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 pasted 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.

In the early 1-2 weeks, all the baby chicks need pre-starter, but few newbie raisers give starter or finisher feed. 

This causes indigestion and various intestinal issues, which is the primary cause of pasty butt. 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

Most of the chicken raisers buy chicks from far hatcheries. I always order clicks from big hatcheries, but they are about 200 miles away from my house.

Sometimes giving excessive amounts of vitamins and electrolyte supplements to dehydrated chicks cause a pasty butt. 

Always provide clean cold water to your dehydrated chicks for a few hours, then offer them electrolytes. Also, do not switch on the brooder for a few hours if the room temperature is average.

Parasite infection

In certain conditions, you may see pasting in chickens because of parasitic infections. Worm infection in chickens causes a lack of nutrients absorption, and it 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.
