My boyfriend and I recently (2 weeks ago)got ducks, first two Magpie and Rouen hens, both pairs under 6 months. Two days later we got 4 Mallards, of which we were told one was definitely female, the other three possibly male. No definitive age on them, but I'd guess approximately 4 months for two of the "males", and maybe 6 months for the female and obvious drake. My question is, the day after we got the second four, we found and egg, but search as we might, there have been no other eggs since then. Any ideas on why? BTW, these are our first ducks, so we are very much newbies. Thank you for any help/advice you can give.
