Hard to tell. We've canopied off their run so we can plant the garden without them eating our starts or seeds. We also shortened their run so we could get on with planting. The relative shrinking of their run is bound to make them stir crazy. My switching their feeding to myself hand feeding from using stationary feeders in the past also factors in. So they're always a bit stir crazy anyways, then more so when they think they're gonna be fed or are being fed. I throw the feed this way and that, from one end of the run to the other, giving them exercise, making them hunt and work for their food. Still they jostle each other abruptly intensely. I should feed them in the run immediately prior to stealing eggs in the coop cuz they loom over me as I stoop down for the eggs, giving me that creepy Hitchcock feel. Plus I got a rooster that attacks me and did today as I was gathering eggs. This gives rise to questions about broodyness. I thought they would continuously sit on eggs they want to hatch, so I wouldn't see them to pick them up anyway. I heard the hens switch off sitting on a few fertile eggs, giving all but continuous incubation. In short I dumped the pile of bones and broth into a pile in the run. They all dove on it. That's all I saw, was busy and turned away otherwise.
