So, I have 13 21-week old hens (Born around Easter). I am getting eggs from 3 of them. (1 EE - green & 2 SLW - one lays on ground) I have several SLW's who are toying with me. They lay in the nesting box squawking their hen song most of the morning/day and still no eggs. They even preen their nests around them. Arggh! I swear I'm not going to buy more eggs...
