It does seem that your mongolian horse can breed with the common horse
Which disproves your claims about number of chromosomes.
How do you explain these massive coal fields, how is not these massive coal fields not supporting evidence of the biblical flood, etc
Massive coal fields are easily explained by conventional theories, but the eplanations of YECs are laughably simplistic and wrong. Massive coal fields cannot be explained by a flood. There is no way that enough vegetation to produce those massive coal fields existed on Earth at one time. The "floating mat" theory of coal formation requires mats thousands of feet thick covering the entire Earth. Therefore, these massive coal fields are evidence for an old Earth and not evidence for a world-wide flood. See

Do you have examples where different kinds of creatures are interbreeding, like a fish breeding with a bat, or a whale breeding with a fish, etc...It would appear cladistic evolution has to explain these problems,
If such things happened that would be strong evidence against the theory of evolution, which predicts that such things will not happen. Since such things don't happen, there are no problems to explain.
However, I've never seen a creationist explanation for ring species, where subspecies A can breed with subspecies B which can breed with subspecies C which can breed with subspecies D ... but supspecies D cannot breed with subspecies A! The evolutionary explanation is, of course, that the subspecies are on the way to becoming separate species which cannot interbreed. For example, the Herring Gull and the California Salamander. See
