It is a 12-14 week old rooster that weighs about possibly a Leghorn Rooster.
He is actin weird he cannot stand or walk, nor can he eat anything and is steadily cold.
He has been experiencing the symptoms for about 2-3 days now.
No other roosters are like him I did have one die right before he started acting this way.
He may have an injury on his legs as to why he can't walk or stand
He has been drinking water through a syringe but cannot open his mouth to eat.
His poop is a little bit runny different from the other I can say that.
I have wrapped him up in a blanket to keep him warm and every 5 minutes get him out and check on him.
The bedding is in my dogs cage in the house with chicken wire around it and puppy pads and some hay underneath them.

What's his diet?
How is he housed?
What are his symptoms?
He'll be warmer outside then in blankets.
