Cocoa seems to about half the size of the rest of my ducklings, with the exception of her look alike but she is still a bit smaller than her. Do poultry have runts? see is eating and drinking fine, she is just tiny. she is the small chocolatey one in the middle of the pic her again
For a long time, Norie was a the bigger duckling while moxy was tiny... Now full grown our Mox is a huge butt and Norie is tiny.... It could just be that cocoa hatched a little later in the day than the others so the others had a head start. That's what we figured with Norie and Moxy
Your little guy really does remind me of Moxy as a duckling. Norie was the largest of the 7 ducks we got in that shipment and Moxy was the smallest by a long shot. Norie was nearly twice as big as Moxy during the first week. Moxy caught up after about 12 weeks and kept growing long after Norie stopped. Now Moxy is around a full pound heavier! (Moxy about 4 lbs, Norie about 3 lbs). Unless the other ducklings are picking on your little guy, I wouldn't worry about it at all.
You have a number of different breeds there - That could in part account for the size difference- if you were comparing a whole group of 50 ducklings all the same breed you would still get variances- but more likely when you have different breeds. You mentioned yourself that the other one the same colour is also a bit small.
