Twins? Two heads? Something else?

My day 2 double yolk egg already has a spider forming, one can say..."Maybe the hen sat on it for a couple days," but the lady who I got the eggs from had roll-out egg trays.

Oh- I was a day off, my double is on day 4. The second yolk is doing nothing though.

Here is another egg I had that was triple...below

I just had one quit at day 9, yours appears to already be a quitter
On day 8, mine was fine, but the next day it had stopped growing.
First pic is around day 6

Was that only one yolk ?
If so is that why one baby went further but the veins and blood supply wouldn’t be enough for 2 growing embryos ?
