This is probably going to sound like a dumb question... We have 5 chicks that are 3+ weeks old and it's finally warm enough to have some outside daytime play. Do we need to put them in some kind of enclosure when we take them out? Will they run/fly away? Please be gentle lol... I am a first time chicken mama. I have done a year's worth of research before getting them but I want to make sure that we don't lose all of our chickens lol...
