Ever since growing in their wings, my chicks have been flapping and fluttering around as much and as often as possible. I'm absolutely positive in their little brains they believe they're real, flying birds. Either way, I almost had an incident in which Goose, one of the chicks, flew out of the brooder. The walls are decently high too, she just barely managed to get on top of the waterer and had the opportunity to hop right out. I've seen them jump up pretty high with excitement as well but again, I believe the walls are decently high and would find it rather uncomfortable to go any higher. What's the issue? Should I get them some toys to distract them from their flappy antics? I was going to start providing a roost even though they're a week old-- they already love perching on our fingers whenever we hold them. But now that they're suddenly able to take short airborne bursts... I'm just not sure what to do to stop them from escaping/getting separated on accident.
