Our two adorable beautiful 8 week old Welsummer chicks keep flying over the fence! We really don't want to get another fence (it's about 2' high), but there are dogs next door and I'm a bit worried. We put them back in whenever we catch them outside the fence, but otherwise they don't seem to know how to get back in! Our heavier Delaware chick doesn't do it... We're hoping these two little gals will be as big and fat as our grown Welsummer hen and stop they flights, but what can we do until then?
