Overview
Red or dark mites seen on chickens at night are often poultry mites, and the most common concern is northern fowl mite. These mites can live on the bird and are often easier to spot after dark, but other small insects or bits of debris can look similar, so it’s worth checking both the birds and the coop carefully.
Things To Check
1. Check the birds at dusk or after they’ve settled, especially around the vent, under the wings and along the breast feathers.
2. Look for tiny moving specks, feather irritation, scabs, skin redness or birds preening more than usual.
3. Inspect perch ends, nest boxes and cracks in the coop, since mites can be easier to spot on pale surfaces or paper.
4. Check whether more than one bird is affected, as mite problems often spread through a flock.
5. Notice any changes in egg laying, appetite, weight, energy or pale combs, which can suggest the birds are being bothered.
6. See whether the birds seem worse after being in the coop rather than when they’ve been out and about, which can point towards an environmental parasite issue.
7. If you can, use a torch and a white paper towel or cloth to make small dark specks easier to spot.
Common Causes
Northern fowl mite is a common cause of red or dark mites on chickens, especially if you notice them on the bird at night or around the vent and feather bases.
Other mites or small external parasites can sometimes look similar at a glance, especially if they’re active in the coop and moving onto birds after dark.
In some cases, loose dirt, feed dust or dried skin can be mistaken for mites, so a closer look in good light can help narrow things down.
What To Do
Start by checking every bird in the flock, not just the one you first noticed. If one bird has mites, the rest may need checking too.
Clean out the coop thoroughly, including perches, nest boxes and corners where debris collects. Pay attention to cracks and joints where small parasites can hide.
Keep a brief note of what you’re seeing, including where the mites appear, whether they’re on the birds or mainly in the coop, and whether any birds seem tired, pale or off-colour.
If you’re unsure whether you’re seeing mites or something else, try to collect a clear photo or sample if you can do so safely, as that can help you describe the problem more accurately.
It’s sensible to keep a close eye on the flock over the next few days, especially if the issue seems to be spreading or the birds are getting more irritated.
