I think that the 2 most important things I have to have on hand at all times is B-complex and Calcium Gluconate! I guess not everyone has egg bound problems but I sure have with one of my girls and sometimes I see another with it too but mostly it's my little Eva. It's like a miracle fix for them and it's nice to have when you need it. Keep it refrigerated after opening by the way. Actually I keep both in the frige.I hope she is not egg bound but these ladies gave awesome advice if she is.
