I have a pair of lovebirds who are currently sitting on 4 eggs. I candled the eggs and one of them has a tiny little black thing on the side of the inside of the egg. There is a single long red line extending from it. Is this a sign of embryo death because i cannot see any more blood vessels except for the one red line?
thanks

How long have they been sitting? ive never candled eggs myself so dont know, but you'll need to leave them until they either hatch or abandon the eggs now anyway.

Average incuabation is 23 days, and you will need to keep the nest moist, spray a couple of times a day. Or spray mum when shes out so she takes some moisture back in eith her.

Dont forget lovebirds also pair up in same sex pairs so are you sure you have a male/female?
