I wouldn’t put a 100% guarantee on either of them at this age, although the first one at the very least looks very cockerel like. My EE cockerel took a lot longer to get the male specific colouring coming in but those bright red shoulder markings on your first bird, well. Lol. The second could go either way - my initial thought was pullet based on the pattern but with the comb and the hint of red that seems to be coming in on the wings, hard to say. Wait another couple of weeks til they get a bit better feathered. the comb on my guy was misleading so I wouldn’t use that as a for sure sign either.
I wanted to update so others can use for reference. One of these boys are crowing and I now believe I have 3 Roos from my pullet order. The last picture I believe is also a roo because of the uneven pattern and the larger comb.
