Need tub ventilation advice

I am in the process of switching my western hogs to a tub setup to free up rack space. I'm not sure how many ventilation holes I'd need in the sides of the tub, if any, as I am planning to remove sections of the lid and replace them with screens (I feel confident on how to safely do this.)

Will several screened lid squares be enough ventilation or will I need more holes down the bottom of the tub as well? TYhttps://uploads.tapatalk-cdn.com/201...6a8288f9e0.jpg

If you have sections of the top removed and replaced with screen then that should provide plenty of ventilation.

That should be fine; even just one square of screen is enough for adequate airflow. I would start with one and then add more as necessary to achieve desired humidity and ambient temps. If you add too many initially you will have a hard time keeping the right conditions.
