Dear Shahin.
Thierry has already answered your question, in that unless you provide a within-family standard deviation for each
"development.overall" or "egg.size" observation, there is no information about familial random effects. You can examine paternal
and maternal contributions, since some of these are repeated across families (in your example data),
but you will not have a lot of power, I fear.
