Our guess after all the help here and from other sites is he ate something, though I don't know what. He's now "star gazing" but he actually has been pooping, and tried to stand, so I thought maybe he's just in pain and not paralyzed? I left a message with a traveling farm vet, he's a little far but at this point I am now concerned about him in pain.
We got Gardstar dust, and also are using food grade diatamatious earth in the coop. He actually let us dust him, lifting his wings and everything like he enjoyed it, so we were hopeful. But this turn for the worst is disheartening.
Thank you for your help, a lot of people say we just need to kill him quickly but this is my daughters beloved pet, so I am letting her take care of him to feel she's trying everything before he passes. She is 11 and has raised him from hatching since 7 years old. He is such a good rooster, and its due to how she's raised him. I hope this vet can at least give him a peaceful passing, as he is really flailing a lot, flapping his wings, his comb has way more purple/grey totally (yesterday it was just a small bit on the back end of the comb) and he is syringe feeding/drinking and pooping. We are giving him arnica and some other homeopathy, as we've done this with them for years after reading about the use of homeopathy from a chicken vet. Just trying to make him comfortable. If he is in pain we are hoping the arnica can at least ease suffering. He is sure getting a lot of love and care right now. I'll see if I can get a pic or video to post.
