We are new to duck keeping and got our first ever ducks in may this year we got two Indian Runners un-sexed which the sellers had kept in three partitioned sections, the first section was aged 1 to 7 days, the second section 1 to 3 weeks and the third section was for 3 to 5 weeks old so we only have approximate ages for the both - our first is now aged anything between 15/17 weeks and the other anything between 14/16 weeks, neither have sexually matured yet. When having realised some time ago both are drakes, we bought Khaki Campbells - what we believe are females - however at the time of buying we were told they were ten weeks old which would have made them both 13 weeks old now but it has been brought to our attention that a mistake was made and that one was only 6 weeks old and the other only 7 weeks old at the time of buying which means one is only 9 weeks old and the other is 10 weeks old - They have formed a flock and a very close bond so we are not going to change any of them but my worry is that if the drakes sexually mature in the next couple of weeks or so, am I right in thinking the hens will be too young to be mated with? (in two weeks one would only be 11 weeks and the other 12 weeks) If so should I separate them straight away or would I be ok to wait and see - the reason I ask this is because the females scream their heads off if we take any of the flock away and will do so if we take their boys away. Would appreciate as much help and advice on this as possible please
