It's the struggle with loving fragile beings. Sometimes we can swoop in and help them heal, but all too often there's nothing we can do. We lost our barred rock a few weeks ago, and I miss her vocal self. In early summer I was able to treat her successfully for egg yolk perenitis, but EYP tends to be a secondary issue and whatever else was going on caught up to her with only one day of her looking unwell. We do the best we can while we have them.
While we don't hatch and just buy day old pullets, I'm not sure we could not not get attached. When we first got chickens together (I grew up with them, and my husband only had a small amount of experience from a relatives farm), my husband assumed when the hens laying decreased that we would butcher the older birds. While there's nothing wrong with that, I informed him I'm an egg rancher, not a farmer and I wanted to let our older birds just be birds until they passed of age. He harumphed and said we will see. Things worked out with our first batch of chicks that he was their primary carer. Around the time he had to clean a stuck vent and give nourishment with a dropper, he informed me our chicken meat was only coming from the store and our retired layers had residency for life. Something about those silly birds makes it hard to not get attached.
