It would be rare for the chickens you sell to have a worse life than if they were in a commercial poultry farm type of place.
Please let others enjoy your chickens. Some of the Show Quality and Heritage Breeders won't give up their stock for similar reasons. The thought is that the person getting the chickens needs to be "worthy". Sadly, everyone dies and if you don't share your project with others, that project will die with you.
I know it's hard.to let go.
Also, let your Son make some soup! . Growing up, my Mom would say: "It's time, go pick a hen that is not laying and we will have Chicken and Dumplings". Boy that was good.
I have birds that are NOT for sale. My special girls. So, I understand your attachment. However, there are people who will take good care of them just like you do. Look at all the wonderful caretakers you find here on BYC. Many of my customers that I have sold hatching eggs to, this isn't even the chicks, keep in touch with me and let me know how the chicks are doing. When you are overrun with chickens, then you will feel ready to hatch and SELL. When you see the delight of little children picking out their special chick. . . you know that chick will have a loving home. Until you are ready, enjoy your birds, I love watching mine everyday.
I know I have to get there some day. Once I do it I will get over this fear of letting go. LOL It is really harder for me than letting go of my kids. I know that my kids were going to be able to take care of themselves. These little ones are dependent on people to care for them. The older I get the worse I get because I have seen more I guess. I am working on it. LOL
