My 2-year-old hen laid an egg with a bloody streaky inside the egg and a blood-tinged egg white. We're not talking about little red spots; this was a streak that was about 1.5 to 2 inches long. The outside of the egg looked fine. Since this happened a couple of days ago, she goes into the nesting box but hasn't laid an egg. No roosters around, so this was definitely an unfertilized egg. Thanks in advance for any thoughts on what caused the bloody streak and whether I should be concerned about her.
