One of my welsh harlequin female ducks is starting to do the flat duck.. I have a cayuqu drake and a welsh harlequin drake. I have noticed tha the cayuga male has been trying to mate.. My male welsh harlequin is clueless so far.. I have two more females one welsh harlequin and a female cayuga.. they are 18 weeks old this monday. I let them free range in the morning and evenings.. Did not plan on starting them on layena for at least another month.. surely she won't start until after I start her on it.. or can she find enough food free ranging to make her start laying.. I also give them mazuri waterfowl maintence mixed with some oat groats.. twice a day. they find a lot of snails etc in the yard also.
