I gave her probably 3 doses a day for the first couple of days. Then I gave her a dose a day for about 10 more days, just to be on the safe side.1ml of cal glu if she has been egg bound a week then give her a second dose. then wait till in the morning if she hasn't laid by then give her another dose. When @Aunt Angus had her duck egg bound it took several days of Cal glu before she laid but she did.
