2 definitely Gravid, another in full glow

[Annarose15]

so does the glow come before or after the ovulation?

Glow happens when they are nearing ovulation. If you go to Marcus Jayne's website, they have a very descriptive timeline of the breeding process in their breeding section. Helped me a bunch last season.
