Situation: I have 3 almost 6 month old splash wyandottes I've raised from chicks. Today just got a beautiful 2 yr old wyandotte roo and 2 more 2-3 yr old jens coming out of molt. I live in SC so it'll be warm for a few more months. What is the likelihood that one or more of my 5 girls will go broody and successfully hatch any chicks? Do they stop going broody when it gets dark at 6 pm in winter? I intend to let nature take its course and not do an incubator etc. Thanks! Total newbie here.
