Strange Egg Veins during Incubation

[FenrisMau]

Hey there, I'm on day 7 of incubating my shipped-in duck eggs. This is our second time doing it, the first time went pretty well. Temp is at 99.5 F and humidity at 55%. I'm afraid there was an issue with it being too hot outside during shipping, as I'm located in the south and it's summer now. After they arrived, I let them sit out for half a day in room temp, when Im thinking they shouldve gone straight to the incubator.

So on this day 7, only one has veins and it's this one. It doesn't look right to me. The veins look healthy though, not shriveling up, and in fact they've grown from yesterday. All 3 photos are of the same egg. Does this look like a blood ring to yall? Might he survive?

I will candle again on day 10, and throw out the bad ones, hopefully that doesn't mean all of them...

Looks like some strong veining. The big clear patch is the air cell. They can move to the side like that during shipping, but usually it’s not a problem.
