I realize that you are probably very angry right now, and feel that many of us have "put you down" and the like. Please stop, take a breather, and listen to me. No one is trying to rile you up, or anger you, or intimidate you, insult you, or anything like that. We are simply concerned for you and your chinchillas.
Please follow the advice that has been given, please do not assume that people are automatically being mean because you are an inexperienced breeder. Many people who are not familiar with experienced members on here mistake sternness and seriousness for rudeness. Lots of people here are very pro-learning-to-breed, the only catch is that they are pro-learning-to-breed-the-right-way.
You have said that everyone has to start somewhere, which is true, but the way you have started breeding not a good way to start. It is, however, a good way to end up with a severely injured and/or dead chin. I am not insulting you by saying that, I am telling you the truth. Like others said, chins are very finicky critters and can become upset by things that we don't even notice - like vacuuming on a different day than usual, or the sun rose too early, or they don't like the music that's playing.
You should not breed your male. You should not breed any chinchilla whose background you do not know. There are very serious genetic issues that can lay dormant in a chin for many years and show up long after they've reproduced - the only way to guard against this is to know their lineage and not breed animals that have those diseases, but even then sometimes things can happen.
One genetic disease that your male could have, but not be showing, is called malocclusion. This is widely considered a death sentence, because there is no cure. If you do not know what malocclusion is, it is a misalignment of the teeth that almost always has terrible consequences. Often the roots of the teeth will grow into the jawbone, or up towards the brain, resulting in severe pain, especially when eating. Sometimes malo can be maintained with frequent filings and careful observation, hand-feeding, etc, but eventually it will be more humane to have the chin put down. It is a heart-breaking experience, and too many owners on this very forum have had to go through it.
If you want to learn to breed, I beg you to listen to what others have said here. There are a lot of very, very experienced people here (I'm not one of them, I am only a pet owner) who would love to help you if you just calm down and are willing to listen. No one is attacking you, even if it may seem like it. You must understand that many of us see things like this happen way too often, and that's why we get upset. Anytime there is a possibility for an injured or dead chinchilla, many of us will get up in arms. It is nothing personal to you.
I apologize for the long message, but I hope that you take something from it. I wish I could give you more advice, but as I said, I am not a breeder.
One "very experienced" exotics vet told a customer of mine to feed her very sick chinchilla "greens." He wanted her to go get kale and lettuce and the like to feed to a chin with a severe digestive problem. This quite possibly led to the death of that poor little animal.
