totally different in size? This is the case with my two Partridge rock pullets, my two grey silkies (however, I do not know their genders yet, so their case might be simply due to their genders), and I had two buff brahmas (now one). One is a lot bigger than the other! In the partridge rock case, I know they didn't send me batams, since they were the same size when I got them. Are they just growing at very different rates?
