My BCM has been laying about 2 weeks now. I put an egg shaped/sized river rock in each of 2 nesting boxes. I know I usually put one rock in each box. But some days I'd find both rocks in one nest. Thinking I'd just forgotten to put one back when I was cleaning out the box, I didn't ponder about the moving rock/eggs. But this morning, I paid attention. I cleaned out the coop and nesting boxes about 10 a.m., and made certain I moved the rock/eggs back one to each box. Went to check for our single egg of the day about 1 p.m. and the gal was still in the nest box. She did get up and there was her egg, and two rock/eggs. My questions - how does a hen move the rock/eggs from one nest box to the other? By beak - her mouth is not that big! With her foot? There is a divider between the nests, that goes to the roof of the nestbox area. And since we don't really know why the chicken crossed the road, is it pointless to ask why she does this?
