Does anybody know if Ameracuana chicks mature faster than Orpington's?

We started raising our Blue and Silver Orpington chicks last June and they turned into beautiful sweet ladies who are laying regularly for us. About 4 weeks ago we brought home some newly hatched Ameracuanas. They are so far super sweet and inquisitive if just a bit timid. But it seems to us that they are growing and maturing at a faster rate then our first girls. We're not worried or anything, just curious if anyone else has experienced something similar. Do different breeds mature faster or does the time of year that they're hatched have any effect? Sorry if this question is silly but have mercy we're first time chicken owners Thanks in advance

Generally bigger breeds like Orpingtons mature more slowly, but growth can be affected by feed, and breeding, even amongst individuals from the same parents.
