I don’t know about potatoes but a couple of years ago I had four eggplant plants that started in our greenhouse in the spring and by September, were 4 1/2 or 5 feet tall and very bushy. I had them up where the chooks couldn’t get to them knowing they were nightshade. A combination of late summer storm and me not watering them since they had finished fruiting made the pots light enough for them to blow over in the wind. I came home from work and found all the pots down and essentially stripped of leaves. The birds had eaten them to the stems. The next day, I found 2 dead in the coop. I don’t know if they ate the most, were sick/weak/more susceptible or what as none of the others showed any ill effects. I keep mine out of potatoes, tomatoes, peppers and eggplants now, mainly because I don’t have any explanation for the two deaths. It may have been something entirely unrelated, but otherwise healthy 8 or 9 month old laying pullets shouldn’t just drop dead.
