Chicken with swollen and twisted legs but not limping!

Mycoplasma Synoviae (MS) is a possibility. However, there are other symptoms as well. It is also contagious to other birds. If there are no other symptoms in other birds, I'd suspect Articular gout.

There isnt any treatment for gout. Comfort care is all you can provide for your Speckled Sussex. I've dealt with Articular gout in one of my older Buff Leghorn roosters. I eventually had to cull him.

For articular gout, test the uric acid level in serum.
You can give allopurinol tablets crushed in suspension for 10 days and stop for 10 to 20 days. If you use allopurinol every day long term there may be some nutritional deficiency development.
100 mg allopurinol: crush 1 tablet in 10 ml water for stock suspension; dilute 1 ml suspension in 30 ml water daily for 10 consecutive days
This has helped a client's pet rooster very well.
