By the way, the opening in a MHP cave is usually the long side of the frame.
Yes, I agree with the long side or at least open on two sides. This prevents a chick from getting trapped in the back that wants to get out.
@jjulian812 if you want to keep it that way, which is fine for the number of chicks you have, move it forward about 6 - 8 inches so the chicks can get in or out the other side.
Also if you want to prevent your feed from being billed out into your brooder, make a cardboard tray to set it in. This will contain what they bill out and it won't go to waste. I made this with some cardboard and hot glue. The sides are 1 1/2 inches high.
Edit: Nice brooder set up
