See how the second chick has a bigger comb and first has a smaller one? That‘s the difference
Adding to the size, it also has a pink/reddish tint and it’s awfully early for that.
Yep, what they said. The first chick has a very small, pale comb and no visible wattles. The second chick has a bigger comb, he has wattles, and he's starting to get red.And the second chick has big wattles.
