Hello! My first chickens are just about 3 weeks old and growing fast. They are very curious and currently living in the garage in the brooder I made from a rubber made container. I put a little roost in the brooder but ther will not use it. I put them on it but they would rather sleep on the floor. And every time I open the top, they all fly up and roost on the rim of the bin. Do they hate the roost I made? And when can I take the outside for supervised visits? They seem like they wanna break out. But I'm afraid they will eat bugs and are they too young for that? If I do take them outside should I feed them some chick grit? Thanks everyone!!!!!
