Obviously I'm new at this, but could someone explain to me why boxes are needed for laying hens? I mean, if hens are free-range, can't they lay their eggs anywhere? I wouldn't want to be the one searching several acres, but in theory, when the eggs are ready to come out, do they need a box...
My first flock is about 3 months old. When will I know for sure all six are female? I keep watching for someone's comb to be brighter or for leg spurs, but so far I haven't noticed anything different. Is it too soon?
