zlo - no the eggs are meant to go bad wherever they are.
They go old after 7 days, and mouldy after another 7, then 7 days after that, they disappear.
Seasonal eggs do it on a yearly cycle (so after 4 months they go old, and so on)
Old/mouldy eggs are harder to hatch, but the colour increments remain the same. I think.
Plus, obv, mouldy eggs are less likely to hatch than old ones.
2 fails and a nattie today -facepalm-
I think to make up for it, we should perhaps get more hatches?
Say, 2 for merchants, 4 or 5 for ranchers?
I think it would make it a far less frustratiing experience, but we're not meant to suggest having more hatches -pouts-
