Ok, just fwiw, "scratch" is not an appropriate feed for chickens if it's all you feed them. Think of scratch as a treat, like cookies or ice cream. You wouldn't expect a child to be healthy if all you fed him was ice cream, right?
Buy a good quality, age-appropriate feed for your birds. Do not give them extra corn, wheat, oats, or other grains, by doing so you dilute the protein percentage.
Giving small amounts of green produce is ok, but again, too much and you throw off the calculated nutrition in the feed.
For now I'd stick with crumbles, as it will entice them to eat it, down the road you might be able to switch back to pellets (what brand of feed are you using?)
But really, adding grain in just messes things up, I'd really avoid doing that. Pine tar is all very well and good, but ideally you want to fix the nutrition issues that are causing this, not have to treat the symptoms, right?
