My son also plays on a 10u travel ball team. Multiple kids on the team turkey and deer hunt. The other coaches and I discuss juvenile and regular opening days and plan our tournaments around them.
I learned my lesson last year on letting my son hunt in the morning before a tournament. We typically play one day tournaments on Saturdays. On this particular weekend I had already told him we would go hunt the velvet deer hunt on Sunday morning after the Saturday tournament. Well as it worked out rain delays forced us to come back and play on Sunday. Luckily our first game wasn't until 11 or 12 on Sunday. We went hunting and he killed a really nice velvet 10. We then go to the tournament.... He was obviously tired and wore out. He didn't play near as well as what he is capable of. That will be the first and last time we do that.
