My 23 week old golden comet hen has been laying for about 3 weeks and has laid her 3rd double yolk egg (2nd in a row). Should I be concerned? She seems healthy and "normal" otherwise.
I wouldn't be too concerned, as long as she acts fine. New pullets aren't quite used to the whole egg laying process and may have small glitches in their reproductive tracts that cause strange occurences, such as double yolkers
