Hi, I have a red-cross hen who has been lethargic for the past few days. She is drinking a lot of water. we just started giving her probiotic. her poop is yellow and watery with pale yellow curdles (kinda like tiny scrambled eggs). Her waddles are shriveled. I tried feeling her crop and it was full of water, she's been drinking a lot though so that's probably the cause. Her tail is drooped, her whole lower body is actually drooped. She's not really moving a lot and she keeps holding her eyes closed.
We tried opening her beak and smelling it but we couldn't really smell anything.
