I have a few questions about allowing y hens to hatch their own eggs. 1) Can I just let the hens lay until they go broody one their own? Or do I have to collect them make them go broody and then stick all the eggs under her/them? I know its about 12-14 eggs they will want to set on... so that would be collecting for that many days. 2) Do you think have 7 hatching is just to many? 3) What I am most worried about it that I am going to let them go broody on their own, but I suspect they will all lay in one nest.. getting one hen to set, leaving the rest to do the same with the next set of eggs so they will all not be setting at the same time.... if I am explaining that correctly lol. 4) How long will they remain fertile on my counter or other location with a steady temp?
