Looks like my easteregger and barred rock in the second pic ( could be the leghorn roo) and the 2 white ones are most likely california X (leghorn) with a leghorn roo. ( could be Barred rock but I dont see that). The adult hen in the pic is NOT related to anyone, she is just the foster mom. Combs seem big but leghorns are big in both roos and hens.
