Help please really sick cockerel i don't want to lose him

my cockral is really under the weather he has problems sitting and is cold we have brought him in and dried him off but he's cold to touch and is just standing in the box with his eyes closed  the other chickens he was with have no symptoms i have checked his crop and it's empty he's about 2 years old  he would normally be crowing and chasing the hens ! he's very sleepy is not eating or drinking i have tried to give him some warm water by syringe i dont know if this is the right thing to do please help

his comb and wattles are fine saw him yesterday he was ok eating but not quite himself then today he collapsed and that's when my husband brought him in he's been standing in his box with his eyes closed how often should give him some warm water to drink? i dont have glucose just sugar and honey i'm afraid i don't trust vets as they don't have a clue have had problems in the past with hens and vets so would rather try and save him or put him down myself .

if you cant find one in our list try looking at this list from the omlet website. you really do need to get him to a vet as he could be in pain.
