Hello, we have 2 Chanteclars and 2 Orpingtons that have stopped laying (well we get like 1 every couple days out of the 4). They are just over 1 year old now. We live on the central coast of California where we have had a couple hot days, but this last week has been mild summer weather. Any clues? They're eating egg-layer crumbles with oyster shells mixed through...appetite seems good. No feather loss noted at this time.
