One of Swedish Flower 5 week olds does this. But he/she also moves around a lot and uses the leg fine. It is always the same leg pulled up.
Hi, I'm no expert, but learning and willing to think it thru with you!
It may be nothing...or she may have landed wrong, and started to protect 1 leg that was sore.
We just added a ramp recently to/from the roost/poo board, assist our larger or possibly prevent injury in an occasional egg bound bird. Many people use ash on roosts to deter mites, and DE, ash or lime, in coop corners and on poo board.
If she's staying in protected areas more than usual when it is not windy...and nothing scary around - it may well be time for an inspection - both of roost area - and flock.
Have they had a dry place to hang out and dust baths lately?
Have you been able to look at her legs, feet, skin and vent area - to look for signs of bites, bugs or irritation? Are there red spots or raised scales? Swelling or off smells?
Get pix of anything that seems off so others may be able to help.
If she's been bitten by Mites at night, or injured when pecked, you may be able to head off infection before bumblefoot sets in, with an anti-bacterial spray or warm saline or epsom salts soak of feet and legs.
It may be nothing but a chill in the breeze...but good for you for being attentive...if she can trot to you for a treat and otherwise has perky posture with raised tail and smooth feathers, proper food, clean water and healthy poos - probably mean she'll be fine!
