If you want to breed sounds like you have a willing female. If not, let her nurse her young a bit and use them for your smaller snakes. THEN once they are gone or weaned, feed mom to a snake.
I don't normally get attached. I do respect certain traits and genetics and try to save them whenever possible. I have produced manx and striped rats. These rats did not stay with me. They were found homes elsewhere to be cared for. A good adage is: a diamond to me belongs on a saw blade. But the Hope diamond belongs in a museum.
