Pastel males are awesome, nobody's saying they aren't...just that if they're B grade and babies, and you have an adult, A grade male already, why would you want the babies when you can get breedable adult females instead? Supply and demand, really. She has a large supply of them (relatively speaking) and thus a low 'demand'---she doesn't really want them at the moment. Not that the pastel boys aren't valuable.
Personally, in her situation, I'd do it in a heartbeat.
And besides, this way someone who really WANTS those pastel males will get them. It'll be a good situation for everyone.
