I have 2 indian runners male and female...I bought them last july at a farm show. The female has not layed an egg yet... It's on layer pellets all these months. When I bought her she looked to be about 4 months atleast. Owner said she was about that... do some ducks just not lay eggs? makes no sense! eats very well, both of them. i know they are both male and female cause they have complete different quack sounds...one is hoarser and one is louder.
