Pale comb, lethargic, and dropped wing

[Dyann47]

I have a black mottled Duccle' roo that is a very sick little dude. I have noticed that his comb had started to become pale over the past couple weeks and I figured it was due to the chilly temps we have had, but yesterday he was staying alone and close to the pen when I would them out. He would swagger over to get water but then just stand in place and "sleep". I can just pick him up without him making any fuss. I have brought him inside to monitor and I gave him a shot of antibiotics that we had for another chicken. He seems to have dried crust on his beak at the openings and when I clean it seems to be somewhat runny. It smells pretty bad as well. I'm uncertain if his crop has soured. I went to check on him last night in the pen and he was too weak to roost and was just sitting by the food bowl. I feel that he may be too weak at this point to fight off whatever he has. Any suggestions on treatment? Thank you!

He sounds like he may have a respiratory disease such as coryza, MG/CRD, or infectious bronchitis. Since he smells, it may be coryza. He will be infectious to your other chickens, and most respiratory diseases make carriers of all in the flock. Most of these diseases cannot be cured, but symptoms may go away for a time with antibiotics, then come back. Culling, then disinfecting the coop and run would be prudent.
