They can't pause between batches since the worms just do what they do, on their 6-7 week cycle.
Evidently they have somebody even less intelligent than you running the operation in Vietnam. There is no need to have 6-7 weeks per cycle for the BAM1 hybrid. Just breed twice as many of the parent lines as you need for a BAM1 cycle, cool half the eggs for a couple weeks, have a hatchery hatch the eggs and send out to contract growers as they need them every 4 weeks. It doesn't make any sense trying to grow out the BAM1 hybrids in the same facility you are breeding silkworms at. They should have had way more than enough eggs to grow a 1 ton batch of BAM! hybrids per month every month by the 3rd generation if those cocoons they showed for the first batch in Vietnam were all of the F! and F2 parent line cocoons they had, and they were split evenly between the two lines. That includes culling 90% the first 3 batches of parent lines for quality control. I also don't know why you couldn't cross breed the majority of the culled cocoons to produce the BAM1 hybrid eggs. There didn't look like there were that many reject cocoons on those flats.
It's obvious from the video why they aren't producing that many though. I haven't figured out how they are going to fit that many worms into 4 chawki trays. They aren't even close to having that place set up to produce that many cocoons.
