6.5 week old brown leghorn chicks, male or female?

[finlay225]

I appear to have 4 pullets (only a couple on pics) with tiny combs, and 3 roos with large pink combs. But someone warned me that it can be hard to tell with leghorn chicks as the females can have large combs too. But mine just seem so different, but this is my first hatch, so put some pics on for your input. Many thanks

There are 3 cockerels and a pullet in your pictures.
