Obviously, I'm not Brian Smith, but I can answer a couple of your questions. I have had Burmese breed in the past, though I do not consider myself (nor do I want to be considered) a breeder. Mine started copulating in October, and the female laid her eggs in the first week of April. So from the first copulation to laying took a little over six months. I removed the female from the eggs with no problems. My big girl was sweet as she could be, and she always let me remove her eggs. She hissed and fussed and put on a good show, but she never once offered to bite. So I wouldn't say she guarded the eggs. She would try to bluff me away from her, but when I showed her I wasn't falling for it, she let me get the eggs. A day or two after getting the eggs from her I would offer her a meal, which she always took. From then until the next fall she would eat like a horse to fatten up for the next go 'round.
I must also confess that I never really tried to breed my snakes. During this time, both my male and female were in the same cage, and when the temperature cooled a bit in the fall they just mated on their own. So I never really had a structured breeding program; I just had a pair of snakes that bred every year. Sadly, I lost the female last October, so I won't be having any eggs this year.
