HELP my rooster is throwing up!

[Acresofchickens]

Hello,
I have a rooster and he is throwing up and he won't take any food or water. Any ideas of what this is?!
Thanks soo much!

Does it smell sour? Is it liquid or feed? Could something he stuck in his throat? Sour or impacted crop?

Thanks for answering. He passed away on Sunday
