When do chickens start to lay? I thought I knew the answer, but not sure and I can't seem to find the same answer when I search. If they are raised in the fall/winter, do they lay sooner? What if they are raised in the spring/summer? They are mostly Bantam, if that means anything. Japs, Cochins, Silkies. Welsumers are the only big chicks I have. They are 3weeks from hatching[lol] to about 9weeks old.
