Other 'commercial' eggs
I'm told in some places you can also find
- emu: 700-900g
- Colors: Green, grey, blue, black
- ostrich 1400g (1.4KG)
- duck: 65-125g (average 94g)
- gull (1 to 2x's the size of a normal chicken egg, a delicacy in England and Scandinavia)
- pheasant, larger than quail, smaller than chicken. olive-brown to blue-gray
- turtle, I suspect these vary in size depending on the size of the mother.
The colors listed are the ones I've seen, if you know of others - let me know, I'll update the chart.
Funny side story: My 4 year old (at the time) was at the zoo with me and some others. There was an ornithologist who had an owl egg on display. The ornithologist asked my 4 year old: Do you know what this is? She looked at the egg, held the egg, looked puzzled up at me but said nothing. The ornithologist said (helpfully) do you think it is a chicken egg? My 4 year old looked at the ornithologist and replied with a disgusted tone of voice 'No', then hesitantly looked at me again and said 'It's kind of like a Muscovy egg'. The ornithologist laughed and said 'Yes, you are right, it is a lot more like a Muscovy egg than a chicken' Further discussion was; The sheen on the shell was more like a muscovy than a chicken and shape of the owl egg was more like a muscovy than a chicken - but the shape was what made my 4 year old unsure - it wasn't quite right for a muscovy egg.
