I have 8 shipped eggs under my broody on day 9. I also have three wouldn't fit under her in an incubator. I've been candling the three in the incubator and finding it harder than expected to tell what is going on in the light brown shells. There is no point disturbing my broody till it's at the point even I can't miss what's going on but since the eggs were shipped and I had one broken and found a hairline crack in another one in the incubator I have a good chance there are eggs under her slowly going rotten. So my question, how far into the incubation do they become a risk of exploding? Our weather is quite mild here being the first month of spring. If I wait till 14 days is the chance of a mess still quite low for both oozers and exploders?
