When can guinea keats go outside?

[overeasyRI]

I have 50 french guinea keets. They are about 3 weeks old now, but are already flying and perching.

When can I put them outside in a pen and when can I let them free range?

I keep them at the same standards as I keep chickens. They are from warmer climates too, so I figure 8 weeks before they can be turned out. And YES guineas LOVE to free range! They'll roost in trees too if you want them to...sometimes if you don't want them to..

Mine ignored their coop completely

I know, I tried to finally gave up on trying to coop up guineas they still wanted the tree..But they will sure lay eggs better free ranging also ...
