I've got four 22-wk. old pullets and it looks like 3 out of 4 are with the program! I'm surprised to see it, given the fact that it got down to 9 here the other night. Figured they would be slow starters and all. It's a little hard to see in the picture, but "Slacker" doesn't have as red a comb as the others. In two weeks, we've gotten 21 eggs total. Here's a pic of the last few.
