I have recorded my white leghorns weight being 2.3 lbs at 13 weeks old but that ones comb looks big to me to be 13 weeks old. Are they all supposed to be the same age?

not really they are very similar in size but two of them have slightly smaller combs so they are probably around 3 or 4

Here are my records. The weight isn't going to be a good indicator if they are sickly or something but can give a general ideal of age. I can't guarantee my scale is 100% accurate either since I have used human scales and fish scales.
