Our newest ducklets will 5wks this Sat. We're considering moving them to be part of the flock come next week when there 6wks? would this sound about right? Currently there kept in in a cage placed inside our night time housing along side the other ducks and we have had them in a 'playpen' outside where the older ducks can be right beside.. so they somewhat 'know' them. The current flock is two drakes, two hens and there 14wks as of yesterday.
