I got 7 free bantam Cochins and an EE a couple weeks ago and have had them in quarantine. Yesterday I let them out their cage to wander the yard with my existing chickens and they are out today too. I was out playing with them just now and I was noticing the "flaws" on them so I guess I got this guys culls. One had a crooked toe hidden in his feathers, anothers tail was wrong, etc. Well I was picking them up and examining them and I noticed ones nose was plugged up. I worked the plug out and some clear fluid came out and it smelled horrible! Like something dead and rotten! I noticed a couple others had the same nose plug thing and the same clear fluid was came out when I unplugged them. Others looked fine and they are all quite energetic and running around eating. Now I'm worried they have something bad and my other chickens could of caught it. They are back in isolation and will stay there till I decide what to do with them. Most of them are roosters and we were planning on giving them away or eating them. If they are sick could it hurt us if we butchered them tomorrow and ate them? I wanted to keep the hens and a rooster so what could they have?
