I was trying to clean out the hen house this morning but one of the hens was sitting tight.
Eventually, after several cups of tea and some cheese muffins, (me not the chicken!) she deigned to move. There were two eggs, one normal delicious looking brown egg and this soft shell egg. I have heard of them and found the remains of soft shells in the past but never seen one intact. Really quite strange. A perfect brown egg contained not in a hard shell but in a brown membrane, all soft and squidgee, like a very delicate stress ball!
I will leave it for the girls to see and perhaps eat it......
I have no idea who laid it but part of me thinks she was very clever.
