We have eleven birds all about eight weeks old. We have a variety of breeds and really like it! That being said we have three Ameracaunas that were selected at the same time and were the same size when we got them. Fast forward six weeks. Two of the Ameracuanas are the same size as all the other birds we got at the same time. The kicker is the third Ameracauna is tiny, I mean a 1/3 of the size of the others. She seems and acts healthy, fights for worms out in the pasture, has healthy poop etc. Is it possible we have an bantam? Are some birds just that much smaller? We are novices at this so we are looking for help.
