I can feel a firm lump under her belly.
She is eating, drinking, and actually pooping. Poop was water last night but solid this morning.
Putting her back is a good idea if she's alert, active and pooping.It feels like the egg has moved further back towards her vent. But other than that no change.
Hopefully she's will expel the egg, but I have to wonder if you are feeling a lump under her belly if you are feeling the gizzard or if she's laid internally.
Time will tell.
Check to see if her crop has emptied overnight.
Let us know how she's doing.
