• How old are your ducklings?
(How many are they?
What breed are they?)
• How old are the ducks from your flock?
(How many are they?
What breed are they?)
• Do you have sexually mature drakes in your existing flock?
(If so : how many?)
• Do your ducklings and the ducks from your flock already know each other?
(Can they see each other?
If so : since when?)
Please : give as many details as possible.
If ever you have even ONE adult drake in your flock, keep your ducklings separated - at least until they are 4-and-a-half-months-old!!
Also : don't put tiny ducklings together with adult ducks.
Instead, wait for them to be grown up enough, so they are not bullied (or worse) by your older ducks...!
