3ish week olds ducks with babies?

[comptonkids]

Since finding out the breed of my two, I've been wanting 1 or 2 more

I live in texas, between abilene and dfw, it's been very very nice lately
a couple of thunderstorms but it is Def spring/early summer

2 questions
1)should I put any new ducklings I get in the brooder with my chicks
2) if I put them outside with my older ducks, will they get along okay? The older ones are at most 4 weeks old

I would keep them separate - ducklings can fight with each other if they are from different groups. They need to be supervised until they are all the same size, then introduced carefully. Sometimes it is a non-event, they get along fine. Sometimes it takes more time.
