I have some Welsummers that started laying a few months ago. They are approaching a year old now here in December. At first the eggs were nice a dark and speckled so pretty. Well, then I went through a few weeks of no eggs from any hen in my flock. I switched to Flockraiser because I have one pen with baby silkies and adults. I went ahead and tried it out on all my coops. WOW, egg production just sky rocketed. However, my Welsummer eggs are lighter? I read somewhere on here a while back that some people believe corn can lighten egg shell color. Any ideas or experience in this would really be helpful. Not sure what is up with Layenna in my area, but it hasn't been wonderful for egg production.
