Please help if you can. Have a older RIR hen who is wheezing loudly with every breath in and out. No runny eyes. Refuses food and water. Has a small bean bag feeling crop believed to be either acorns or crushed corn. No foul smell from breath or poop. Rubs beak back and forth on ground if we try to feed or water. Tried a tube insertion through mouth and filled with warm water to try and flush crop. Tiny amount of corn came out. (She started pooping on her own after this). Wheezing is still very loud, with head/neck extended up most of the time. No chicken vet locally. Don't believe able to cut her open to empty crop. Any other ideas? Should we just cull and put her out of her misery? She's not "weak" at this point but will be if something doesn't give soon. Also giving VetRx mixed with water on q-tip on roof of mouth plus rubbing head feathers down in hopes it will help this wheezing. No other birds are showing any of these symptoms. She is in isolation currently.
