okay...i have 2 lovebirds.i dunno about the s*x of the birds.they laid eggs.there are 8 eggs once.but when i checked the box last time,the birds scampered and then accidentally,an egg fell off.it is cracked and destroyed so i didn't return it.now,i smashed that egg.there is a yolk inside.the white/yellow stuff.does that mean the egg are inferitle?and also does that mean that the other eggs are infertile too?all the eggs are a week old now....and also,when can i consider that the eggs are not gonna hatch ever?about what time?

p.s:i used egg-production boosting vitamins for the birds

Answer 1

We need to know whether or not they mated, so the genders of both will need to be known first.  We'd also need to know whether or not they're incubating them.  If they're not, then the eggs are most likely infertile.

Based on the information given, my guestimation is that they're infertile.
