Hey there everyone. I have never raised chickens but when I was younger we had some laying hens so I know the basics once they are older. I thought my kids would enjoy the experience of chicks so we have been raising these ladies since they were teeny. We have 3 Americana (?spelling) and 3 Buff Orpington and one of each concerns me that they may be roosters. One of our Americana has always been less friendly, more outgoing, and bigger than the other two. Recently it has started crowing and it is a pretty good crow , but I have read on here where some hens will crow too so I just don't know about that one. Also, one of our buffs has become significantly bigger than our other two and is much less affectionate than them as well. Not to mention that she (?) has developed a comb and waddle way earlier than my other ladies. I guess I am wondering if I will have to wait until everyone is laying before I know for sure? 1st picture you can see the difference between the one I am wondering about compared to the other two buffs that are in front and behind it. Second from bottom picture is of my other two buffs just on their own, you can see how they don't have the bright red comb and no waddle at all yet even though I got them all at the same time and they were all the same age.
