This is the main reason I sow from June onwards, plus the soil is warmer so I tend to get a better germination rate.
If and when you thin them; water in the thinned out carrots by adding a smelly/scented substance to your water beforehand, and this will disguise the 'carrot' smell.
I use Armillatox which has a Jeyes fluid smell and it seems to work. Plus I cover them with a fleece tent from the ouset, as can be seen here;

If you are going to protect then I would do so now.
