Ok this what i have so far the 2 i mentioned earlier in this post with there heads being wider acrossed the top they strut around alot and sometimes they will hold it for 10 sec or more and they are just over 7 weeks and the one that is a little smaller hasnt.these are just some comparisons so far that a naked eye can see.2 with legs that are a little longer,legs alittle thicker its like comparing my pinky finger to my index finger.heads wider and back of heads more bald down neck.So from here on out within the next few weeks what should i be looking for if there toms.If i can get some good footage with my cam i will post it.
