The last one is a pastel, very normal for their heads to be blushed out. How ever that eye concerns me and needs a vet soon. The rest look like normals, without knowing what the parents are, I couldn't tell you for sure if they are normals or not. The one with the kinked tail. I highly doubt will make it. He probably wont be able to defecate. He too will need a vet but they may just have to put him down. No one is ever ready for this type of thing, but if you are not prepared to take them to a vet, then maybe breeding isn't your thing.
