my Maui had infertile eggs also.... they seemed pure yolk after 20 days of sitting on them... so after a few days she had ignored them I tossed them.... later she laid one more egg, which I knew it was a replacement one because she only laid that one......

after like 10 days she started laying again and now we have the replacement one and 3 others... which might be fertile this time as they have been mating in between eggs laid........ hopefully this time we have babies.....

just make sure she replenishes her calcium....and offer dark greens and cuttlebone
