What are the tiny red mites on my chicken coop at night?

Overview
Tiny red mites seen on a chicken coop at night are often red mite. These pests commonly hide in cracks and perches during the day and come out after dark to feed, so they can be easy to miss until the coop is checked at night. There can be other small mites or insects too, so it’s worth looking closely before assuming.
Things To Check
1. Check the coop after dark with a torch, especially around perches, joints, nest boxes and any gaps in woodwork.
2. Look for tiny moving specks, clusters in cracks, or pale grey dust-like patches that could be shed mites or debris.
3. Inspect your birds for signs they may be affected, such as restlessness, reduced egg laying, pale combs or reluctance to roost.
4. Check for blood spots, dark smears or irritation around perch areas and nest boxes.
5. See whether the problem is worse in warm weather, as mite activity often becomes more noticeable then.
6. Look for damp, cluttered or heavily creviced areas where mites may be able to hide.
7. Make a note of how widespread the issue seems, because a few insects in one area may need a different approach from a coop-wide problem.
Common Causes
The most common cause is red mite, which lives in the coop rather than on the birds and tends to feed at night.
Other possibilities include other small mites, lice, or harmless debris that can look red or brown in poor light.
Sometimes dirt, bedding dust or rust-coloured staining can be mistaken for mites, so a close inspection is helpful.
What To Do
Start by cleaning the coop thoroughly, paying attention to cracks, joints, perches and nest boxes. Removing bedding, droppings and dust can make it easier to see what’s really there and helps reduce the hiding places mites use.
Keep a close eye on the flock over the next few days. If birds seem less settled, stop roosting well, or look pale or weak, take that seriously and get advice.
It can also help to review the coop layout. Smooth surfaces, fewer hiding spaces and regular cleaning routines may make ongoing control easier.
When To Contact A Vet
If your birds seem unwell, very weak, pale, or are losing weight or egg production quickly, speak to a vet. Heavy mite burdens can affect birds quite badly, especially younger, older or already stressed birds.
If you're not sure whether you’re dealing with red mite or something else, a vet or poultry specialist can help you work out the next step.
