Reptiles, especially advanced ones, will never have gills, not at birth, not later.

And they can't be completely still as they are in water and need to move/swim to not sink. So the mother can't stay still to put the into the beard. The beard is that thick that it would have problems to put it into the pouch and might miss it what means the egg is lost forever.

And? Whales do it and they would do alright without us humans. So why can't Ceadeus? And the egg laying thing also needs patience and distracts the mother.

And as Ceadei are solitary I doubt that they would stay with each other more than necessary and would wait the laying of the egg.
