PS: I prefer layer pellets over crumbles...they eat it well with less being wasted as much less is pulled from the feeder to fall uneaten on the ground.
I have 10 eight month old pullets and average 9 very good eggs a day. I keep 2 feeders full at all times. Recommend that oyster shell & grit not be mixed with food but rather each being available in separate containers.... They will eat all of these only as needed.
