6month old Rooster limping HELP

[Subie19]

Our 6-7 month old Silkie Roo started limping the other day and now is fully not using one leg. I have examined it several times and cleaned his feet but don't see any sign of any injury. He is alone, with no other chickens or animals, so no possibility of fighting another chicken. I am very worried. Today is day 4. He is not able to walk up the ramp to go into the coop at night or come down in the morning, I have to physically move him. No other symptoms at this time. I am a newer chicken mama. I am stressed and want to help him. Could it be broken!?

Maybe he has something stuck in the bottom of his foot???? Maybe a splinter or a thorn? That's my best guess

The way he moves it looks like it could be injury. You'll have to pick him up, feel of the leg really well and see if you find a break, uneven area, etc.

If vet care is an option, that would be best, an Xray will let you know more for sure.
