Well, none of our local floodbelievers have chosen to take up the simple question of whether or not all the animals in the ark could be cared for by an eight person crew without miraculous assistance. That's not surprising, really, but I do think it says something about the mindset, and I think it's worth tyring to explain why.
Pwengthold offered this explanation:
This is easy. Recall the whole reason for doing any of this is to get creationism taught in schools. However, they know very well that a religious approach of "it's a miracle" means that it can't be taught in public school. Therefore, they twist themselves backwards to try to find a scientific explanation so that they don't have to invoke a miracle.
If creationism were about what is taught in church, there wouldn't be a single issue. No one would care. But it is when they try to get it taught in school that the problems arise.
I think there is truth in that, but it isn't quite correct. They want it taught in schools because they really think it is a real, valid, theory of the history of the world. Pwengthold's explanation is that they try to avoid the miraculous explanation because they know that only a scientific explanation can be taught, but I think their problem is a little bit deeper than that. If it were a simple legal conundrum, they would address it differently.
I think the bigger problem they have with the question is that it invalidates the whole story. The "Bible Stories for Children" version of events (which is what everyone knows) is that God decided to destroy the world, but he kept Noah, his family, and enough animals to repopulate the world safe by putting them on a boat.
This may have seemed pretty plausible to the Babylonian author of the Epic of Gilgamesh, or the Hebrew author who adapted it into Genesis. They probably had no clue about the diversity of life that really exists on this planet, and no clue about the special diet, climate control, and health needs of all of those many animals. They probably had also never tried to manage animals in an enclosed environment with no ventilation for extended periods of time. If you took every animal that the author knew about, they could all fit on a boat, and all be fed, so it would appear to the primitive authors perfectly plausible that a boat would save them all, even if he went so far as to think that the "provisions" would have to include live rats for the four kinds of snakes he knew about, and maybe even some blooming flowers for the six butterflies.
Fast forward to today, and we have a lot more knowledge and experience. We know that there are tens of thousands of vertebrate species and many times that number of invertebrates. We know about the special needs for diet, moisture, and temperature control that are different for so many of those tens of thousands of species.
Because of that knowledge, we know that the ark would be a death trap for most of those animals, not a means to escape the doom that was inflicted upon the rest of their kind. In other words, it makes the story completely implausible, even given the miraculous nature of the events. They can wish away the problems with the law of conservation of matter and the sudden appearance and disappearance of huge amounts of water. After all, the story says that it happened, therefore, it happened. However, the story also says that the boat kept the animals safe. That, we know, and even they know, could not have happened. The boat, by itself, not even with 300 years to prepare and gather provisions, could not have kept the animals safe, but the story says they were safe because of the boat.
That's why they simply can't address the question. It demonstrates that the whole story is fictitious. Even within the framework of belief, it can't be reconciled within itself. The rain is part of the story, so it makes sense within the framework of belief for the water to come and go. However, if you use miracles to keep the animals alive, you are contradicting the story. The boat was supposed to be the miracle, and it was supposed to be all that was required to keep them safe during the flood. That's what the story says. To acknowledge that it was inadequate is to say that the story is really not completely accurate.
