Can’t walk, bloody stool

Anyone experienced where a chicken cannot walk and has bloody stools?

My chicken is in a makeshift chicken hospital bed and he tried to standup after we fed and gave him water yesterday, but he couldn’t stand for more than a 2 seconds

Now he cannot stand at all. Its been about 35 hours since he’s been unable to stand and about 2 hours since he had a bloody stool

Im starting to suspect its coccidiosis(?)
