actually eggs are laid one day yes one don´t one yes one don´t....

so you should be expecting another one soon....

perhaps even sooner as when a female looses an egg she automatically lays another one to fill the "blank".... that´s why they say don´t toss the eggs if you don´t want babies as the hen will produce more and more and that is ot healthy...

just keep feeding her what you are currently feeding so she doesn´t depletes calcium adn they should be ok....

fertile eggs should show some veins when candled (in a dark room place a bright flashlight beneath) I tried doing it with mine, but either I screwed when looking or hey are unfertile as I did not see anything ...

lil yolks are way too cute!!.. I know as I had to throw a few eggs due to punctures and I couldn´t help but look inside... it seemed so tiny and cute!!

good luck... and ((hugs))
