Lol, no, some broodies are persistant.
You dont have to get eggs, if you could get chicks, but if you want eggs, depending on whenever you want her broodyness to stop.
Oh, and can you have a rooster? You could get one and after a few days your hens would be laying fertile eggs (if he breeds them). But it looks like your in the city.
May I comment though your birds are beautiful! We have 2 BR's but their all plucked on some areas, along with some of the other hens, because we always buy from people who overcrowd their birds I guess.... But now their spoiled to death, LOL
