So we got our first egg yesterday I think. We found two in the coop but, one was broken and, I assume it was from yesterday cause we were gone most of the day and didn't check. My two oldest pullets are now 16 weeks I think. We got them when they were " two months plus" so I'm not sure. I heard one of them scratching around in the coop and I saw the eggs. My younger pullets are 12 weeks old. I heard that when a pullet lays an egg I can go ahead and switch her and the other older ones to the layer feed, even the rooster. But what about the younger ones? Can I change them too? Or how am I supposed to separate the food?
