I agree, I would set up a laying bin for her if you don't have one yet. Especially now that she has her mature yellow spots. Also, I don't know if you dust her food that heavily with calcium all the time, but it's usually best to only dust them so they are just one shade of color lighter. The bugs shouldn't be white.
Thanks for all comment
Yes she has a laying bin.
She is eating well (Everyday with Calcium and Once a month with Multivitamin)
But she looks to have a big belly and gravid color.
Laying has not start yet.
Is this a problem?
