2 days in a row now, I've found broken eggs in the coop under the roost in the morning. The roost is inches away from the nesting boxes (on a different wall) so it's not like they can't get there. And it looks like 2 different hens have done this. When the first one happened, I thought maybe someone had kicked it out of the nesting box, though there is a pretty good lip on it to prevent them from rolling out. They do use the box regularly but these seem to be happening overnight. They are in their coop from dark to about 7AM, then are outside all day free ranging though they have access to the coop & the run all day as well. *the first egg was normal but the 2nd was one of those with a soft shell. I think it's probably the same hen because it's right under the same spot (and my girls seem to have picked out their positions on the roost). The first one was green so that tells me which hen it is, the 2nd was hard to tell because of the soft shell. They do have oyster shell & yogurt frequently along with a complete feed so I'm guessing the soft shell is one of those weird flukes. So my question is: do chickens lay while they are sleeping on the roost?
