Oh, this sounds hopeful!
I think I'd give the Extra Calcium for 5 days instead of 3. Let's hope is she's got another egg or more material in there, she'll be able to push it on out.
Are you still seeing the watery blood?
Keep me posted.
I would give her 1 Calcium Citrate with D3 tablet for 3 days, just pull down on the wattles and pop the tablet into her beak and let her swallow.
You may want to get a Permethrin based poultry spray or dust to treat your birds and housing if the Poultry Shield is not effective.
Likely the blood is from straining to pass lash material if she has a mass to expel. Sometimes they may be able to pass the material, sometimes not.
I'd try giving her extra calcium for 3 days to see if that helps with contractions so she can push better.
It doesn't sound very promising if...
