Well, I am not at all that great at telling breeds, but that fourth pic down from the top looks like a blue laced red wyandotte?
Don't know how old the pics are but they all seem too pink in the combs and wattles for laying. The combs and wattles get real red - you can't miss it - when close to laying time. Also, you can't hurry it, I'm sorry to have to tell you that cuz I know you want those eggs!
1. Partridge Wyandotte or Plymouth Rock or even an EE
2. Buff Orpington
3. EE
4. Splash Laced Red Wyandotte (occurs when two BLRW are bred together)
5. Buff Orpington
Compare your first hen's picture with a picture of a Black Sex-link or a golden laced wyandotte ....your cross hen should start laying earlier. Ours were hatched in March and we are now getting eggs every day from the sex-link hens. But they will start showing more comb and the color will be deeper red. As for the squat...if you don't want a rooster, just give them a shake with your hand on their back and they will be happy.
