I had an idea to make cockatrices "realistic" (as in make a bit more sense) for what ever reason the noble cockatrice has evolved to use other species eggs for its own. It does this by "sitting" on usually a chickens egg. When it does this it inserts it's own embryo into the egg.



The cockatrice embryo proceeds to eat the chicken embryo and uses the nutrients in the egg to gestate. Once it gestates the cockatrice would scamper away into the wilds.



Would a parasitic embryo like this work? Could a cockatrice replace a chicken's embryo with its own?

    Good question, I should think an answer might need to take into account any inherited immune system (or just plane reservoir of antibodies) that a minimally developed chicken could have access to in ovo, protecting any punctture of the shell and membranes in the replacement process - re-sealing the egg to prevent infection...... etc.

I'm by no means sure of this, biology is not my wheelhouse, but I would think that the most likely "solution" in this case is that the Cockatrice reproduces by introducing a live-born predatory infant into the eggs of prey species. This tiny creature then burrows into the shell, attaches itself to the inside to seal the egg and halt evaporation and then simply kills and eats the chicken embryo and grows inside the shell using it as protective camouflage almost like a hermit crab until it has developed sufficiently to fend for itself.

The tachinid flies have a similar mechanism when parasitising butterfly eggs:




Illustrative genera include: Exorista, Voria, and Plagia. Many Tachinid eggs hatch quickly, having partly developed inside the mother's uterus, which is long and often coiled for retaining developing eggs. However, it is suggested that the primitive state probably is to stick unembryonated eggs to the surface of the host.[7]




From Wikipedia's article on Tachynidae https://en.m.wikipedia.org/wiki/Tachinidae



Despite the distant common origins of flies and butterflies, the parasite feeds well off the egg content of the host butterfly.
