Would this be a good haiku?

Wisconsin snow falls
Gently and softly like rain
The children go play

Yes. It looks good to me. :-)

I mean thank you! What about these two?

The wild animals
Are very protective of
Their natural home

The sunlight is nice
For us to see in daylight
And helps us keep warm.

Would any of them contain symbolism? If so, which one and what?

To determine if a haiku is good, we can follow the traditional structure and themes of this form of poetry. Haikus are a type of Japanese poetry consisting of three lines with a syllable pattern of 5-7-5. They often focus on capturing a vivid and concise image of nature or the seasons.

Let's count the syllables in your haiku:

Wisconsin snow falls (5 syllables)
Gently and softly like rain (7 syllables)
The children go play (5 syllables)

The syllable count in your haiku follows the 5-7-5 structure, which is good. In terms of the content, your haiku depicts a winter scene with snow falling and children playing. It seems to capture a peaceful and innocent moment.

In conclusion, your haiku is structured correctly and describes a suitable subject. It can be considered a good haiku.
