My hen is doing the same thing!! No shell no white, just a yolk. Did it ever work herself out? Mine gets more ten enough calcium and all my other hens are fine.
It is either a yolk only egg or and shell less egg.
In the 60 years my grandmothers has had chickens she said this was only the 2nd time she has ever gotten 4 from one chicken in one day. Normally it is only 1 and occasionally 2 if you are lucky... But it IS possible. Which I think is the coolest thing ever!!
Just got our first egg today from our mean chicken Peppermint, we have 3 barred rocks that are 23 weeks old, Peppermint, Baker, and Cookie... and 2 Production Reds that are 3 weeks old named Sweet Pea and Nugget. One awesome dog that protects them as well as gets chased by Peppermint. Took that...
Recently my grandmother had a barred rock that had a really good week. One day she laid 4 eggs the next day 3 then the rest of the week was laying 2 a day. She was her only hen at the time so is how it is easy to figure out it was her. Pretty cool. Think the world record for one chicken was 8...
