Is this how a healthy 1 day old egg (or less than 1 day) is supposed to look like? Those lines are on the actual shell..you can see the yolk inside near that dark patch. So, is this a normal egg? Or is this why the mum chucked it out of the nest today?

not too sure about this, might be an idea to ask Kaz she will most likely know

I've had a few like that, place it back in the nest and give the hen alot more calcium and protein to make better eggs... some never get better, but some thicken up with fertilisation and the process of a chick growing in it... place it back and see how it goes i'd say...

I agree with Libby.
