Not as a Predalien thing. Having an alternative method of reproduction for a p̶r̶a̶e̶t̶o̶r̶i̶a̶n̶ young/molting queen like Chet was before it could lay eggs isn't that bad in theory. But I would have preffered eggmorphing instead of eggbarfing, since the latter eliminates the need of eggs/facehuggers, making it too easy of an asspull to increase the aliens numbers.
It should have had setbacks that would make egg laying more effective in the end, start by removing the multiple bursters thing.
