Go to any grocery store that has vitamins/supplements... ever heard of CitraCal for people? That's calcium citrate you can give her, generic brand is just fine...
Thanks, Kathy! I worry about egg byproducts running around willy-nilly inside a bird, way too easy for bacterial infection to happen... :hmm
X2 on the calcium, calcium citrate absorbs quickest and best, ime...
Look up EYP, that's egg yolk peritonitis... that can happen when an egg breaks inside a hen... also a possibility when the egg is shell-less and membrane ruptures... check her for abdominal swelling...
@casportpony am I on track here?
