Lovemychickies,
Is your question really about culling chicks (best described as the killing of ill-formed or otherwise undesirable birds, shortly after hatching) or are you really asking about processing meat birds for the freezer? These are two distinctly different things and both terms, frankly, are too kind for the brutal realities involved.
Culling is absolutely essential to the overall health and conformity to breed standard, if that is what your aim is. To me, it is far more difficult to do because of the age of the bird being killed. I wish it was more like line-breeding with dogs, where you can just spay or neuter the dog, then sell or give them away.
Processing meat birds, butchering chickens, is not a fun process either, but it's also nowhere near difficult or challenging. It's incredibly easy, truth be told. The struggle most people have with butchering any animal is the emotional turmoil they feel when killing something they have spent months, or years, nurturing. It seems like a contradiction to care for the well-being of your birds, then be the cause of their demise.
I would argue that this is not true: Chickens have been bred to do one, possibly two things, well. They are intended to provide a large volume of eggs, a large volume of meat, or a significant amount of both. To assign a different value to a chicken is like asking your dog to purr or your cow to run the Kentucky Derby.
I'm sure I will be thought of, by some, as heartless or even cruel, but the most accurate term would be "pragmatic". Enjoy your
for all that they are and all that they offer.
