How far along is she?

I know the gestation is around 24 days, but does anyone know how far along a doe is when she starts showing? My female is getting pretty big and wondering when I should put her in the birthing tub.

thanks

Dave

If you do like I do and use maternity tubs AND If they are waddling it's past time to pull, lol.
Generally as soon as they swell noticeably I pull them to their own tub.
