wow, sorry it has taken so long to get back here.
there has to be an easier way to learn this thing.
checked the hen last night and this am, no sour smell no burping, just alot of pouch happening, hasn't gotten any larger or any smaller.
not sure about the sour smell never thought to check but will when i put them to bed. it is much larger than the others crops and i have seen those larger at night.
glad you are out there to help us new eggs!
thanks
