I'm picking up 11 Buff Orpington and Gold-Laced Wyandotte chicks TODAY! They will be about 2 & 1/2 weeks old when I have to leave for a trip (for 2 weeks). I have a nice large brooder set up, with a decent run area; 6'x10'. I have some wonderful neighbors who will be babysitting the chickies. My question is, at what age are the chicks able to fly? The run area is fenced about 6 feet high, but not covered with wire fencing. Do I need to worry about the chicks flying around by the time I home, when they will be about 4 & 1/2 weeks old? I wouldn't think so, but like so many here, I'm a first-timer at raising chicks.
