It has been HOT here (upstate NY) for days/weeks and our remaining 3 have stopped laying. "Remaining" because our other 2 were killed by a fox on the same day. The other 3 haven't laid much since. 2 are nearly 3 yrs. old, a golden laced wyandotte and a buff brahma; the third is 4 and is a buff orpington. Does the heat slow them down this much? (I don't recall this in past hot summers) or is their age also becoming a laying issue? If they saw their sisters get killed would it freak them out that much? We have been keeping them in the pen much more ever since and they don't love that (we let them out for a few hours if we are outside and can see them.)
