Wild chickens

[Hotzcatz]

Another way to mark the eggs is with "X"s and "O"s. Check the nest and take out all the eggs marked with an X's but leave all the O's and then mark the unmarked eggs with X's. The next day take out all the O's and mark the unmarked eggs with O's. That will get all the eggs within a day of being hatched and they can sit there for up to three weeks without any harm as long as a hen doesn't go broody and start to sit on them. Or put a date on the eggs, then you will know when they were laid.

If you give feral chickens a comfortable spot to roost, a nice dry dark place to lay eggs and some food, they will stick around. As they hatch out each successive generation you will get tamer and more domesticated chickens again.
