We have 3 chicks so far! and maybe out 8 more eggs with pips and some zipping going! We have a total of 38 in there. Our eggs are really really dark so when I candled them before lockdown it was difficult to see if there was movement in there...there were definitely chicks taking up most of the egg in the 38 out of the 48 i kept.
One of the chicks looks like it has a dried up gray mass stuck to it along a little string....maybe an umbilical cord to the dried up yolk or something? It's getting around just fine and hopping along the eggs like the other two...is this ok?
Goo and poo. It should pull off.
