I first took my daughter duck hunting with me when she was 4. Girls are different than boys and I am sure he will be into at even at 4 so should be no worries. Ava liked it but it got cold when the sun was setting. Oh yea, I missed 5 GWT that hunt
. Last season, when she was 5, she enjoyed it much better and went with me a couple times.. If he wants to go, bring him, he should love it.
