This creates a very large egg for your poor hen to lay. The second oocyte then travels down the oviduct and has albumen and a shell deposited over it and first egg together. the previously released egg which was in the lower portion of the oviduct before reversing course) is typically added to the oocyte that was just released into the oviduct. This counter-peristalsis contraction, resulting from the premature release of a second oocyte into the oviduct, causes the first egg in the eggshell gland to reverse its course and be pushed back up to the top of the oviduct. The release of a second oocyte into the oviduct system while a first oocyte is in the eggshell-gland portion of the oviduct (the eggshell gland is also called the uterus in a hen and is where the shell is deposited over the egg) causes a contraction. A counter-peristalsis contraction is when a second oocyte is released by the ovary before the first egg has completely traveled through the oviduct and been laid.
