How to Treat a Chick's Pasty Butt (or Pasted Vent)

Raising chickens can come with a lot of risks and health issues. One of them is your chicks developing a pasty cloacal vent. A chick's vent needs to be dealt with and cleaned up as soon as possible or it can result in death. Follow our guide to get started.


  1. 1
    Knowledge yourself on a pasty vent. You may have heard of something such as a pasty vent occurring in baby chickens but do you know what it is? A pasty vent is when the chicks vent (from which it's waste comes from) gets clogged up with faeces. When this happens you need to act fast as it can result in death.
  2. 2
    Locate the affected chick. Affected chicks are usually distinct so you shouldn't have a problem. Grab the young chick and then place it in solitary confinement or go straight to cleaning it up.
    • The chick needs to be separated from the flock as soon as possible due to the fact that the other chicks might peck at the affected area and inflict further injury.
  3. 3
    Prepare the chick for clean up. Collect two containers, a cloth, baby shampoo and a towel. You'll also need to find yourself a warm room, free from drafts. A room with a sink is best suited such as the bathroom. Kitchens can also be used as long as nothing gets contaminated.
    • The two tubs you acquire should be able to fit the affected chick and your hands but yet you don't want it to be too big as it isn't necessary.
  4. 4
    Fill the containers and prep the towel. Fill both containers with warm or lukewarm water. One needs to contain soapy water whilst the other must be free from soap and bubbles. Spread the towel out, ready for the chick to be dried.
    • Make sure the containers aren't too deep or big for the chick. It should just about cover the chicks vent but not it's head.
  5. 5
    Put the affected chick in the soapy container. Begin to rinse the chick with the water. If the chick isn't affected badly the vent will clear right up. If the vent doesn't clear then you'll need to intervene by rubbing the affected area with a damp cloth. Baby shampoo may help in this case.
    • Another option is to clean the chick up by simply placing it underneath the tap and rinsing the affected area. This can be less effective but is worth a try.
  6. 6
    Move the chick to the remaining container. This container shouldn't have soap water in it because you're going to rinse off the soap suds from the chick. You may need to use your hands to help rinse the baby chick.
  7. 7
    Prop the chick onto the dry towel. Wrap the chick up and begin to dry it. Don't cause too much friction and certainly don't suffocate the chick in the towel. Make sure it can breathe and that it is fully dry before it is taken back to the brooder.
  8. 8
    Take the chick back to it's brooder. If gone for too long you may have trouble regrouping it to the flock. Make sure the chick is fully dry so it doesn't catch a cold; which can happen and is fatal.


  • There's not a set way to prevent a pasty cloacal vent but you can make sure your chicks have plenty of access to their water bowl. The more fluids they drink the less pasty their faeces get.


  • Chicks can die from pasty vents. You need to act fast to treat it or this will happen to your affected chick.
  • Do not leave chicks unattended by the water. They have a risk of drowning, especially if the water container isn't shallow enough.
