We got a small batch of Wyandottes (and a few others but they didn't make it) and added them to our flock of older birds. We got rid of a few of our older birds because they were 4 years old and had decreased their laying to nothing. Now, one of our new birds is a rooster. So we have two flocks in one group. The older birds and a roo, and the younger birds and a roo. In the coop they are fine, the Roos don't fight (pecking order is well established). When they free range, the younger girls stay around the younger rooster and the older girls stay around the older rooster. It is winterish- so my older girls just finished molting and aren't laying. They haven't laid any eggs since like May of this year (they are 4 years old as well but I didn't want to reduce the size of my flock by too much in case I had a new roo.) my new Wyandottes are also not laying at all. We got them as day old chicks in April. Added them to the rest of the flock slowly in June once they were feathered. What could be our problem? Is it the lack of daylight? Is it the split flocks? Are the younger hens scared to use the older hens nesting boxes? What can we do to try and get eggs? It's been almost a year and I'm so ready to quit buying chicken feed AND eggs.
