We find a note from August 1919 about these experiments, reading 
as follows: 
„Contrary to the Sonnerat-bankiva hybrids those of varius are very 
difficult to raise. Of the eggs laid only 15% on an average hatch, the 
rest is not fertilised or the chicks die while still in the egg. As a conse- 
quence the experiment 393 gave this year but one chick, with a smooth 
comb like varius and this one died, when a month old. On the other 
hand experiment 197 gave 9 chicks, 5 of which are still living. In 1918 
the fertilisation was poor also. Only two chicks were born in that year
