Hi all! I am a new chicken owner and my 6 chicks are 7 weeks old. They are starting to get bored in the coop (10 x 12) and I am wondering when they can start to free range. I live on about 5 acres and since I don't have any older chickens to show them around I am wondering if they will get lost. Is it ok to let them out now? We are working on getting their run finished but it is taking forever. Thank You!
