So, I just found out that while at the vet, they weighed in her at 1lb. 1lb! That would be a severely underweight hen and I'm shocked that no one questioned this. I weighed her several times last night and this morning and she's averaging about 4.4-4.5 lbs. That means for five days now, she's been way under-dosed on her antibiotics. I'm pissed! I'm waiting for the vet to call me back with the correct dosage and I'm really hoping that she'll start to improve once she's on the proper dose.
