Coturnix or Japanese quail statistics and numbers

I've become interested in coturnix quail.  I've been doing a lot of research to find statistics and measurements for them.  I thought I'd put it all in one place.

a good guide to hatching:

Brooding
1 day - 2 weeks: in the house
2 weeks - in shed
3 weeks outside, still in brooder
4 weeks in adult cage

Heat: heat plate (watch this closely because they grow really fast and their height changes quickly.  If they are huddled in the middle the plate is too high or too cool (if using a rheostat)

Chicken care coloring book

When I went to Idaho Chickenstock last year, I had a great time.  I also noticed how many children were there, both buying chicks with their families and just looking.  I thought it would be fun to have a coloring page or book that children that explained how to take care of chicks.  My daughter was nice enough to illustrate it for me.
