I went out to the coop this morning, expecting to find a few eggs in the nesting basket.... Instead I found one hard-shelled egg, completely covered in poo under the roost and one soft shelled egg, also under the roost... My girls get free choice of oyster shell and crushed up egg shells so Im not sure what could have caused the soft one. My three RIRs are 6 months old and none of them have ever had a soft shelled egg. The only explanation I can think of is that the soft one came from one of my EE pullets (4.5 months old). Theres no shell on it, not even a thin one, so I cant tell who it came from. Anyone have any explanation to why they would have laid an egg while on the roost? I saw them go to bed last night and once on the roost, they never get up while its dark.
