Hello all! Newbie here with 7 backyard hens. Recently a few of the hens have been jumping the fence of their normal enclosure. I thought it was relatively normal behavior and maybe they were just looking to munch on some fresh grass, but today I found that at least three of them have been laying eggs in a secluded part of the garden (I found 7 in total!). Their house has a large nest box area but they don't seem to want to use it. Any idea if this is normal or if there is any reason behind it?
