Still cockerels :( I was just wondering if you perhaps also had created sex links. But your leghorn must carry barring if the hen was definitely an australorp - it's not uncommon, it's done to get them to have the bright yellow legs they are supposed to have.
Unfortunately it looks like both are roosters :( The barred one definitely if your rooster was the australorp and the hen the leghorn - the leghorn must carry barring and so if that one is the hen all chicks hatched from her would be barred if male, and not barred if female. This will be 100%...
