There is no doubt about this. We've watched it a bunch of times ourselves because we didn't believe it at first. Like I said, sometimes the eggs are exactly the same and sometimes a little different size.
Here is the chicken and the eggs! She continues to give us 2 eggs 5-6 days out of the week and 1 egg on her "rest days." It is over 6 months now and she's showing no signs of stopping. Eggs are sometimes the same size, sometimes a little different. Both shells are always good and eqq quality...
I have a brown red ameraucana hen that has laid 2 eggs most days for the last 6 months and shows no sign of stopping. Is this an anomaly or is there possibility of breeding this trait? Thanks.
