Id do serious things for 20% pellet. Maybe try to talk up kings?
I think avacado is a pit and skin issue? Rubarb is a big nono. The love tomato and strawberries fresh corn and will seriously kill your children for pea plants ( the plant over the peas. I gave up on peas they went to herculan feats to get at them. ) they like carrot if they are bord and seem iffy about squash.
I have heard if the plants are big they can survive chickens . If your tomatoes grow 4-5 feet tall you can let them debug. As long as there is no peas...
The 4H Poultry leader when my grand daughter had her chickens said that the roosters had a problem with too high a feed & shouldn't even be given the amount in lay pellets/crumbles that it could cause the roosters to have a leg issue. I house my chickens in breeding pens so everyone gets the same feed plus the supplements I use. I haven't noticed a problem. I do see the red line down the roosters legs but am assuming that to be a fertility/breeding line.
