I meant to say larger animals - it's been tried. Small fish and frogs were fine, but chicken eggs showed issues developing past some early stages under microgravity[1]. Therefore we know that animals significantly more complex than amphibians can not reproduce normally under zero-g. > Twenty out of 30 eggs (nine out of ten 10-day-old eggs; 10 out of ten 7-day-old eggs; 1 out of ten 0-day-old eggs) were recovered alive after landing. The only living embryo of the 0-day-old egg died 24 days after launch, and was comparable to a 16-day-old embryo when it died. The high mortality of the 0-day-old eggs appeared to be related to the specific inner structure of the egg. The yolk (specific gravity, 1.029) would not have separated from the albumen (1.040) during space flight. 1: https://pubmed.ncbi.nlm.nih.gov/9600757/ https://pubmed.ncbi.nlm.nih.gov/9600757/ ( https://archive.is/r66W3 https://archive.is/r66W3 )
