The lump is different for sure. I agree with @MissChick@dee continue to soak her and give her a clean up. Hopefully the lump will reduce in size.The top of the vent feels a bit hard when I touch it. When I press on it slightly it causes her to poop a bit, seems like a reflex.
As for her crop, it still feels somewhat golfball-like in the mornings, but strangely it seems to soften up and shrink after I give her a tsp of coconut oil. Very strange.
It's hard to say if there's a smell coming from it, as that poop/diarrhea is fairly smelly and it took over the bathroom.
Any suggestions as to what to offer up for the diarrhea? I wonder if it's partially stress-induced.
I would work on the crop some more - it should not be golf ball sized in the mornings before she eats/drinks. Cut out all treats that need a lot of processing at this time (no scratch/sunflower seeds, no veggies, etc.). Offer her only wet feed. She can have some scrambled eggs for a treat.
The coconut oil is fine, but massage the crop several times a day.
