Why are my hens’ legs becoming thick and bumpy?

Overview
Thick, bumpy legs in hens are commonly linked to scaly leg mites, which can make the skin on the shanks look raised, crusty or rough. Other causes are possible too, so it’s worth checking the legs closely rather than assuming it’s one thing straight away.
The main clues are how the skin looks, whether the hen is itchy or uncomfortable, and whether one or both legs are affected.
Things To Check
1. Look at the scales on the legs. Raised, crusty or flaky scales can suggest a mite problem.
2. Check whether one leg or both legs are affected, and whether the change is getting worse.
3. Feel for heat, swelling or tenderness around the shanks, feet and joints.
4. Watch for scratching, pecking at the legs, restlessness or signs that the hen is uncomfortable.
5. Look for broken skin, bleeding, scabs or areas where the scales seem lifted away from the leg.
6. Check the feet and toes as well, since foot damage or irritation can sometimes happen alongside leg issues.
7. Consider whether the flock has had recent changes in coop hygiene, perches or bedding that might be contributing to skin irritation.
Common Causes
Scaly leg mite is one of the most common reasons for thick, bumpy looking legs in hens. The mites live under the scales, which can make the skin look lifted, crusty and uneven over time.
Old skin damage or dry, irritated skin can also make the legs look rougher, especially if the hen has had minor knocks or has been living in damp, dirty conditions.
Less commonly, other skin conditions or infections may be involved, particularly if there is swelling, heat, discharge or obvious discomfort.
What To Do
Start by examining both legs in good light and noting exactly what the skin looks like. If the changes are mild, keep a close eye on them and check whether they spread or become more uncomfortable.
Keep the coop clean and dry, and make sure perches and bedding are in good condition. Good routine hygiene can support recovery alongside any treatment plan.
Avoid picking at the scales or trying to scrape the legs yourself, as this can damage the skin and make things worse.
If you have more than one hen, check the rest of the flock too, since similar signs can appear in other birds.
