When Should I Candle Eggs & Could There Be Twins?

[SGExotics]

we candle ours as soon as we get them from the mom to check for vaines,and once a week after that..and the egg size doesnt indicate twins,,just good fat eggs,but can always hope and ya never know

Oh, thanks! I thought there were twins because the eggs are huge haha, but again thanks for the help!
