Anyone have any ideas on the older chicks and now my new ones all the help is appreciated!

The brown ones look quite a bit like my Speckled Sussex pullets. But one of yours is definitely a cockerel.

I think I maybe leaning more towards a Welsummer now too instead of partridge rocks....

So the chick in picture numbers 5 & 7 on page 3, the younger chicks, which are golden and silver laced wyandottes, is that a boy..none of the others have combs like that one yet? And the original 3 that are still being debated are in the first 2 or 3 pics, which are my oldest chickens. Then the youngest ones are golden comets.

If noone is exactly sure which breeds my oldest chickens are in the 1st 2 pics on the bottom of the 3rd page, is there anyway I can tell later like egg color or some other way to find out?
