Yep... all sorts of variations happen once in awhile.
The ones I love the best are the REALLY teeny eggs a hen will lay once in awhile. I'm not talking "pullet size" or even "robin size" eggs... I have had three or four over the years, which were about 3/4" long!! The first time it happened I thought maybe a wild sparrow had decided to use the nest box for a nest.
The strange thing is, these are perfectly normal eggs inside.. people told me they wouldn't have a yolk, etc...
Not these.. teeny tiny yolks, white.. everything there. I've been told they absolutely won't hatch. I'm still tempted to try it. Can you imagine a race of chickens about 4 ounces at maturity!
