14. (6 points) There are 100 chickens and rabbits in total, and the chickens have 26 more feet than the rabbits. So, how many chickens are there?
71
【Solution】Solution: Let the number of chickens be $x$, then the number of rabbits is $100-x$. According to the problem, we can set up the equation:
$$
\begin{aligned}
2 x-4 \times(100-x) & =26, \\
2 x-400+4 x & =26, \\
6 x & =426, \\
x & =71,
\end{aligned}
$$

Answer: There are 71 chickens.
Therefore, the answer is: 71.
