It's because I love them so much that I am considering any possible future turtles' lives of 60 years, and all the consequences involved with allowing eggs to reach maturity/hatch. If I cannot care for them myself, then I do not want to contribute to the pet trade (I've worked in veterinary care and rescue for too long). That's my own personal choice and opinion; like I said in the original post, I know many people on this board are involved in the trade, and I am making no judgments about this - to each their own.
For me, personally, I could not be a part of something my animals have all come out of and ended up in rescue/homeless/facing euthanasia from; everyone here has their tales of woe from mistreatment/abuse to simply being unwanted. Too many turtles end up sick/dead after years of suffering from incorrect/improper care, or in rescue after they are no longer wanted (and also after improper care), or going from home to home to home over the years, which I find is too stressful for achieving optimal wellness, even if the care is correct for the species in each home (unlikely). How many people do you know that keep turtles with the correct habitat and husbandry for the entire lifespan of their animals? Put them in their wills and make arrangements for them after they are no longer able to care for them? Not very many. I'm sure the people on this board are exceptional in their commitment to their turtles - but, sadly, this is uncommon.
My box turtles (3-toed) are not native in Northern-CA. It would be irresponsible to release them here. If I lived somewhere where they are native, I would be more than happy to move the eggs to a suitable location in the wild, or to raise the babies to the point where they could be responsibly released into the wild. This would be ideal with wild populations on the decline in many places. I would love to do it, but it's not possible where I live. If anyone knows of a reputable native population program that will take eggs for eventual release to the wild; do let me know!
When eggs are 1-day old you have no idea if they are even fertile! They are certainly not developed enough to be considered "babies" - not to me anyway - but I'm not going to get into a discussion about this (unborn rights, abortion, etc.), as I feel it is completely off-topic and far too emotional and inflammatory a topic of discussion. Removing the eggs at this stage is the most humane way, IMO, to manage my own turtle (and bird) populations. You may make other decisions for the animals under your care - and that's fine. I completely respect your carefully considered choices to ensure you are making responsible short-term decisions for the long-term consequences associated, with your own turtles.
Destroying eggs at this stage is much like removing chicken eggs to eat; the difference is the turtles are not brooding (and unlike birds do not care for their young), so I feel it's probably less stressful on the adult turtles to have their eggs removed from the nest. I don't eat eggs, but it's not killing anything at this point, IMO. Allowing them to hatch and then giving them away/selling them, the truth is, I probably am killing them that way - it's just going to take longer for them to die after years of suffering. I could only give offspring my own turtles produced to someone I knew would be responsible for that turtle for the next 60 years, and was totally committed to providing correct habitat and care, and if not, then to return the turtle to me. And I'd want to stay in touch for the life of the animal to make sure these conditions were being met. If I had to room to keep more than two turtles, I would allow for whatever number I could handle to reach maturity/hatch (if they are even fertile, which we don't know). But I do not. I live in a dense urban environment, where very few people even have yards at all - two turtles is the most my tiny yard can comfortably and properly handle.
