Well two Drakes after one Hen isn't good..Ok they didn’t mate but this is the first sign I’ve ever seen and two what I know now are drakes were both biting the back of a head of a duck and one drake bobbed his head up and down for awhile then got on her back but only for a second they are 18/20 weeks old now and I’ve not ever seen an egg
I also read mating season isn’t until March
