So apparently "chicken math" doesn't apply just to chickens. It also applies to ducks! We recently were gifted a couple ducklings in addition to the 4 pekins babies we just bought. Realizing we had a duck run plenty big enough for a few more friends, I made the mistake of going online! So now we have 6 more babies on the way. They will be 4 weeks younger than the mallards and 3 younger than the pekins. Should I put them all together? Will my big gals hurt my little ones? Is it best to brood separately until older? Thanks for your help!
