well we all do have different opinions...
IMO,,, first time flock..
i would skip the leghorn.. they lay eggs but are very fighty and "active" (aka high strung)
and the welso and wynd .. just get one of each
get more buffOrp & rocks
what about RIR???
and for a first time flock, feed store chickens are JUST FINE.. untill you get a little more info and have them around a years or so and decide WHAT breed you like best... THEN invest in some good quality birds..
you could spend $42 ,for 12 birds,,,on feedstore chickens,, have several different breeds and they will help you learn..
or you could spend $160 ,,for 12 birds(like i am planning on)...for ONE breed, and then you decide you hate that breed and need to start over...
and if your neighbor dogs rips a hole in the coop and kills them all..... or a skunk.. or a coon... or a coyote....
get the cheap chickens and LEARN. make sure you pick out healthy babies..
then in a year or so, get your DREAM FLOCK
