How many ducks can I have?

[jacca5]

I have two rouens now but am building a 8x8 pen and I wanted to get some more. How much room do they need and how many could I put in the area?

If you were closer -I'd fill it up for you-- but if that us ALL the room they would have- no free ranging-- 4 at the max is my guess.I would leave space for a kiddie pool-

I already have a kiddie pool that they use now. Four sounds fine I do want them to have plenty of room. I can't let them free range I am affraid something with happen to them.
