We are new at this, had 4 Indian runners since July 2012 and this spring the females started to lay.
We collected until one day when one female started to sit and we left her alone for the fours weeks. The eggs did not hatch and when examined they were not developed. We removed the old eggs and were expecting her to begin laying again.
It has been 3 days since we removed the old eggs, she is back to her regular behavior with the other ducks, BUT has not laid since??? How long before she will begin to lay eggs again???
