All at the same time in early March of last year. That's why I tell people it can happen at any time!What time of year did you get them?
Of my 4 EE's (sadly one died suddenly a few months ago) only 2 lay green so I know she wasn't laying because I finally had gotten another green egg! All along I was assuming she was laying a brownish egg because I figured she had to be laying! But was surprised one morning in January or Feb to find a different colored green egg!!! My EE's are my best layers too!! Even over my Black Austrlorpes!
The first 2 lay green and the last 2 cream. One is a bit pinkish but still cream.
