I have a rather strange question. I am such a NEWBIE sorry all. When sexing your ducklings I read it can get harder the older they get. What if you can not find them at all??? Is it possible to be hatched without ??? I am asking b/c I have a duckling I call No-neck. Named so because it waddles around with it's neck tucked in. Very rarely does it extend it's neck. Anyway this particular duckling seems to have an extended belly. It is soft but I was wondering if it could be retaining fluid or something. It appears to be sluggish, does not follow the pack when they go foraging.Seems to just sit in the shallow puddle. Some times when the Mother and siblings come back it will hook up with them but stay in the back. We can not seem to find it's genitals. So that had me wondering about whether or not if they could possibly be born without genitals??? And if that is not the issue what is going on with it??
