I have three BA chicks, almost 4 weeks old. I know this is generally too early to tell however one chick is not quite like the other two at this early age and seems to have a much larger comb....I have found many other similar posts with a bit older chicks however they have not be updated so I have not been able to determine if this is just early development in one of the chicks (I plan on updating with time so others can learn from this!). The first two have much smaller combs, same age. What do you all think??
