Annabel Posted July 7, 2020 Share Posted July 7, 2020 Hiya, can any one help me identify what these white spots on the yoke are. I have one ex caged hen who routinely lays egg after egg with these white spots (some have rings around them unlike this most recent one) but we don’t have a cockerel so they aren’t fertilised. Do any of you get these? Quote Link to comment Share on other sites More sharing options...
The Dogmother Posted July 7, 2020 Share Posted July 7, 2020 (edited) That's not a bullseye on the yolk, just a normal looking Blastodisc, see diagram below, so not fertilised This photo probably shows it better, although they are both slightly confused with their terms - the label bottom left which reads 'not fertile' should read 'not fertilised'. It does annoy me - sorry '!: Edited July 7, 2020 by The Dogmother 1 Quote Link to comment Share on other sites More sharing options...
