Hi Geoff,
I think in most bird species it takes about 2 days. Once the egg has been
fertilised, the ovum is enveloped by the infundibulum (the site of
fertilisation). Then the outer layers of the egg (cuticle, crystallisation
layers and the eggshell membranes) begin to form. While all this happens,
the egg descends down the oviduct.

Subject: Egg Laying In Raptors
I know there are a lot of knowledgeable people that read these emails.
The question is:
From the time of fertilisation how may days is it till the egg is laid?
If another egg is laid a few days later is it fertilised on another
occasion?
The question is about the White-bellied Sea-Eagle but I am sure there is no
specific info on them but any info on birds of the same size would be of
interest.
Thanks
