Every morning when I get up and around I give my 7 pullets about 4 hands full of popcorn. I keep a hanging feeder with 16% all purpose crumbles in it. They much prefer the un popped pop corn. Sometimes i give em a couple of slices of 100% wheat bread. And today i give em some home grown watermelon. If i give em all the treats will they not eat enough of their regular feed. 4 of them are about 18 weeks old. Will the treats effect when they start laying?
