We are there when they enter the world and we are the one's who must decide their fate when the time comes to let them go. Whether to another farm, or from the bondage and pain of this life.
When you help bring them into the world and then care for them a bond forms. It is a much different bond then you may have with a beloved pet. Just because they are here for a purpose we take our responsibility to care for them very seriously. It is a duty we do not take lightly, when their time draws to to close on the farm, there is always sadness, tempered with the knowledge that they lived well here.
When death gets easy or does not bother us is the day we will give up the farm!
