Hello.
As usual I have a lot of eggs, they even lay in the Roll of mesh that I had left in the pond.
Currently I install a production tank of Daphnias, Aselles and Azteca.
When the fry will be big enough I will install traps to attract flies for their larvae.(My excuses)
I found another study on chicken eggs.
