I'm worried about 2 things with regard to free ranging.... They are 11 and 15weeks old (6 total). So far they have just been in the chain link run, inside my fenced 1acre (hopefully can see from pic). The fence around the acre is mostly 6ft. tall but some of it I am worried about, it's only 4ft with wood around the top (in first pic - looks like a nice place to roost). So if I let them out for some free range time will they really come back to the run/coop at dusk? It seems like a long way and there are trees, 1 heavily wooded area even though fenced. I'm just worried I will have to "round them up" if they wont come back at night. And will they jump/fly over the smaller fence or will they be to happy running around to care? Any advice appreciated!!!
