I hate doing it, but my hen that has been sick on and off for months and months was really going down hill fast. For the past week, I kept expecting to find her dead in the morning when I checked on her. Lately though, reading through posts on here, I realized that even if she somehow miraculously recovered, she could be a carrier of something that might then be passed to the rest of the flock, or permenatly disabled, or perhaps just always prone to sickness, and regardless of how much I paid for her, I just can't justify it any longer. The hardest part about culling a chicken is explaining to the kids. My 8 year old is just heart broken right now, even though I said we would be hatching other eggs and could very well get another one that looked like this hen and name her the same if she wanted to. She thinks that every chicken that gets a name should be kept and loved forever and ever. I am sad as well. I hate giving up on a sick hen, but my success at curing them is dismal, so I have decided that I will probably start culling a lot more quickly than before. There have been too many that have just languished in the house for weeks while I tried treatment after treatment before they finally just died anyway.
