everyone has different flock dynamics. All any of us can do is relay what we do and how it works for us. For me the great part about broody's is I don't have to deal with the chicks. I don't get involved at all. Mama's do it all. I just enjoy the show.Sorry my friends, being newly hatched as I am, I may have posted out of line... I don't have chickens, just ducks! I say Aug 5 because with the weird weather we've been having here (Zone 5), it is just really stressful for me, worrying about the babies without feathers and the freezing temps. Of course, this is such an issue because Mom has decided to be fickle and hasn't been solidly committed. Anyway, that is just my experience, I am 100% positive that all of you know your flocks better than I do!
I would let any of my hens go broody this month. Now my ducks I would discourage until spring. Not that my runner Penelope wasn't a great mom, she was. But being she is my only broody duck experience I would wait until spring to let her do it again.
