Congrats! Every first egg is exciting!
We got our second first egg this morning. I had opened the nesting box and found our RIR in there. "Oops, sorry!" I told her. Then every 10 mins I was at the back door, seeing if she was in the yard or still in the box. I think that she sat on that egg for a while, as it was quite cold by the time she left it there.
You would have thought our BR laid that darn egg, she talked it up so much. the RIR seemed nonplussed and unimpressed with herself.
