Thank you everyone for all opinions, I appreciate them all. I have talked to my dad about what he thinks would be best for the bird, and he thinks to cull him would be the right thing to do. As of right now all I know is something is really wrong with him and that he has not gotten better over the last 4 days, but has gotten worse. It is absolutely heartbreaking to go in there and see him this way.. He was such a big proud rooster over his hens. He is not living a happy life right now guys. He can't walk and just sits in a box all day not eating. I think I will give him until the end of this week ( Saturday ) and if I do not see improvements, we will cull him. I feel at that point it's the humane thing to do. Until then, I will give him all of the care he needs. Continue to try and feed him things, anything he might take and putting some ACV into his water because it could possibly help. Thank you all so much and I will continue to keep you guys updated.
