greenupcountydigger,
Those do look to be doing fine.
I bet you got more rain than we did this year. The heat and dry here has made it tough on my 3 leafers, some look OK, some have just passed on from the heat/dry.
You may want to consider spacing yours out a little more.
You could transplant some of those that are bunched up late in the year, either this year or next. As long as they are looking healthy would probably be Ok to wait until next fall to transplant to thin them out some.
Scotts book says to plant at 4-5 seeds per sq ft, and you should end up with 1-2 per sq ft at maturity. Looks like some of yours is a bit thicker than that.
Good Luck !
