@Leahs Mom maybe you could keep the most mothering of hens and get her to raise the chicks. I think Stony had a favorite broody hen for many years. Makes me wonder if the broody hens keep laying years after a production hen might be done since the broodies don't lay as many eggs a year.
I guess I just need to see how it all works out and make the decisions based on what's going on with the birds I have or want to have. I tend to "worry about tomorrow today" and try to get things all figured out before it comes which often wastes a lot of good time that I could be doing something else!
