So I am a first time chick owner. We have 2 ameracaunas that we're born on Oct. 12 and two barred rock chicks that were born on Oct. 19. They all seem happy and healthy. I just have a question out of curiousity and for learning purposes. The ameracaunas seem to be growing crazy fast, seems like they've almost doubled in size over the past 2 weeks, but the barred rocks are still tiny and don't look like they're growing much. I realize they are a week younger, but I was curious if there's a difference in size or growing rates between the two breeds? Or if maybe the barred rocks are just a week away from a growth spurt? Again, I'm not worried, they are all eating and drinking and very active. Just wondering what you chick raising experts think about their growing.
