Coturnix quail.

Any quai; will work but the Coturnix are the most proficient; they begin at around 6 weeks of age and can really pump them out! They need a good feed and plenty of Calcium, feed the shells back to them.

i used to hard boil them and color them red and green at Christmas time for party trays. When you boil them, keep them stirred to hold the yolk in the center as much as possible, put in a container of white vinegar and the shell will disolve, easier than shucking by finger.

The brown speckled eggs you see for sale in the store --especially in Asian markets-- are coturnix eggs. Bobwhites lay white eggs and not in huge numbers.

I believe some states consider quail of any breed to be wild birds and regulate their keeping. You might want to ask your county's extension office to see if your state is one of them.
