Overview
Pale combs and a tired-looking flock in summer can be linked to red mite, but there are other possible causes too, including heat stress, poor water intake, moulting or another health issue. Red mite are worth considering especially if birds seem worse overnight or after time in the coop.
Things To Check
1. Check whether your chickens seem more tired in the morning, after being in the coop, or after hot weather.
2. Look closely at combs and wattles for paleness, and compare birds if you have more than one.
3. Inspect the coop at night or very early morning for tiny moving specks, especially around perches, cracks and nest boxes.
4. Check for signs of disturbed sleep, such as birds reluctant to roost, restless behaviour or preening in the evening.
5. Make sure fresh water is always available and that birds are drinking normally in warm weather.
6. Look for other changes such as reduced egg laying, droppings changes, weight loss or a scruffy appearance.
Common Causes
Red mite is a common cause in summer. These mites hide in the coop during the day and feed on birds at night, which can leave chickens looking pale, weak or generally run down.
Heat stress can also make chickens tired and less active, especially if the run is shaded poorly or water gets warm.
Low water intake, moulting or general illness may also make birds look pale or quiet. Sometimes more than one factor is involved, so it helps to look at the whole flock and the environment together.
What To Do
Start by checking the coop thoroughly, especially cracks, joins, perches and nest boxes. Clean out old bedding, reduce hiding places where possible and keep the housing as dry and tidy as you can.
Make sure birds have cool, clean water and somewhere shaded during hot weather. If one bird looks much worse than the others, separate your observations by bird so you can tell whether the problem is affecting the whole flock or just one chicken.
Keep an eye on how your chickens behave over the next day or two. If the paleness, tiredness or any other changes continue, it’s sensible to get veterinary advice so the birds can be properly assessed.
