Rooster acting strange, Help!!

[mishella69]

My rooster wasn't feeling well yesterday. He would keep to himself all day and slept a lot but did go on the roast with the rest of the chickens at night. Then today I let all the chickens out to free range and he stayed in the run and wouldn't move so I went to check on him and I stood him up and he started limping so I took him inside the house to rest. He was not limping the day before. He did eat & drink but he is sleeping alot and has very watery diarrhea. Hours later I picked him up and put him on the floor and he almost fell over when he tried to put weight on his bad leg. He just stood there holding his leg up and constantly closing his eyes. I felt around and I didn't feel anything wrong with his leg except its slightly warmer then the other leg. So I have no clue what is going on and now I am scared its something serious and I have no clue how to care for him!!

Please help!!!

I thought he was better today since he seems to be walking normal but he is raising his leg little bit. He is drinking a lot. I put him outside to get fresh air but he is still sleeping a lot. Now I am noticing that his crown is kinda purplish.

Please does anyone have any idea's why he is not feeling well? I want to help him but I don't know what to do. :-(
