We have a female mallard about 3yo. Eating normally (flock raiser and fortified grit) I put her in the coop tonight 6pm and she ate her dinner and was fine. About 1/2hr ago I heard funny noises and went out to find her in respiratory distress. She is gasping for air, opening her mouth with every breathe and there is a wheezing noise that is becoming slightly liquid sounding. Her chest heaves with each breathe. Her eyes are sparkly and clear. Her nostrils were clear until she just tried to drink and sneezed it out her nose. She is sitting and or standing normally. Pooed normally too. I looked down her throat as much as I could but couldn't see anything. We worm her regularly. No changes to her coop, or food. No new critters. I muck the coop daily. I am thinking maybe she is choking on something and wondering if there is something I can do for her. Like the heimlich maneauver or something?? I tried offering her a pea, which is her favorite treat, she took it but spat it out. I currently have her in a cage in the kitchen with her mate, who is not bothering her. She stresses horribly without him. She tries to drink and blow bubbles out her nose, and ends up sneezing. Any ideas or help would be appreciated.
