Double Rubber Eggs

[babybird2003]

Anybody have any ideas on why a first time layer would lay 2 rubber eggs? One right after the other. I know reasons of why a chicken would lay a rubber egg ( young pullet, food, calcium, physically) but just wonder what the science is behind 2 rubber eggs. My hen is a first time layer. She started showing the symptoms of egg binding so I did all the recommended procedures to help and when she did finally lay it 2 rubber eggs came out. My chickens are fed layer feed and free choice calcium. Treats are minimum. Any help is appreciated! If I forgot to answer any question too let me know.

It is probably due to her being a new layer with an immature shell gland, but here are some links that might help you:
