OK. So I am out putting my birds to bed for the evening. The chickens are in and the ducks are in and I am putting the geese away when I hear a ruckus in the hen's coop. I look in through one of the windows and my "Little Dude" (the hen that turned in to a rooster) is having his way with one of the Silver Laced Wyandottes. I have noticed that the hens faces are getting pretty red...like they fell face first in a pot of red makeup. I think this is a sign of maturing. If my rooster is now mating with his harem should I expect they may begin to lay eggs early (16-17 weeks instead of 20)? Should I change their feed to Layer at this point and/or begin giving them oyster shell? I know that mating and egg laying are not reliant on one another but don't want their nutrition to fall short either.
