In Pritchard's Turtles of Venezuela, he states the largest RF (at the time) was a Venezuelan.

There are yellow-only RF's from a particular area of Colombia. There are also 'normal' RF's near by. The orange ones may be interbreeding between the two populations.

If you are hatching these, do not bother the eggs for several days before you expect them to pip. The most common reason I have encountered is too much commotion while the eggs were hatching.

Almost certainly mites. I've not seen them congregate on tortoises before but a little mild soapy water sprayed over them will almost certainly rid the tort of the 'infestation'. You can also use diluted flea/tick shampoo made for cats & dogs - 1 tbsp per gallon should do the trick. You can...
That has little if anything to do with it Yvonne. I let that one die on the vine as I have little inclination to spend the time & effort necessary to put a cogent coherent reply to it and then convolve it to something acceptable in today's mamby pamby my feelings are hurt vernacular. I am...
OK, that's good. In many cases, a blue-green cast in/on an egg means a Pseudomonas sp. has begun to grow - not usually a good sign. Otherwise, the egg looks OK at this stage. If you are concerned because it differs from the other eggs, you could separate it to another container. Was the...
I think you have a rather colorful RES that is coming of age. Unless it changes radically from what it is towards unhealthy looking, I would not be concerned. It may become even more red as he matures.
No argument there, sir! Even as a biologist, my purely scientific perspective appreciation of the definitive mammalian characteristics is shared with you.
