bantam questions?

[tuesdays chicks]

hi all hope I manage to convey these questions right, when I got my chicks I just reached into the box and grabbed the ones I thought were cute and healthy, they were day old chicks, as they grew I started naming the breeds what came out is oegb roo, leghorn roo, andalusian pullet, campine pullet, brahma pullet. I knew the oegb was a bantam because he was quite small compared to the others, well i got rid of my roos at 8 weeks and at the time the leghorn was growing larger compared to the girls, and the oegb was about 1/2 his size. heres where the question comes in now my pullets are nearly 21 weeks old and they are still not even 1/2 the size of my Buff Orp and she doesnt seem to be a very large bird, the only 1 seeming to show any size difference is the brahma.
Can my girls be bantams? the andalusian is now laying tiny eggs that look like they came from a pidgin and to be honest they all aren't much bigger then pidgins** dont know if my spellings right looks funny.
any insights have I just got small birds that are still growing, or could they be bantams?

Andalusian's and leghorns are small birds.Comparing them to a dual purpose of any breed would be like comparing apples to oranges...they are not dual but egg layers.Andalusian pullet eggs like any other pullet egg is very small when they get to full size Andy's lay a large medium to large-by weight size egg they don't lay jumbo like the white leghorn will...those tiny things somehow lay a massive egg...pigeon size birds duck sized eggs makes a cheap layer
Leghorn chicks are often the largest chicks while in toddler stage because they hatch so darn big...those big eggs once again make very big chicks but when tweens hit the others catch up and pass them up in size..
Sounds like you have large fowl to me...
