Is this enough ventilation for my chickens?

[Mangomochi]

I’m curious if this is enough ventilation for my chickens. On the back of the coop i have this triangle vent and the front i have this square vent. I was curious if i should leave the front opening slightly propped open at night for air flow or would the air going in count as a draft to the birds roosting.

Make the vents bigger, atleast twice as big.

How many birds? What are the measurements of the vents? What's your climate like?

Recommended minimum is 1 sq ft per bird but that's moderate climates. If you have hot summers 2-3 sq ft per is closer to what you want.

I have 6 birds but i dont think i have even 6 square total on the top vents. I was just planning on having the front panel open for air and maybe even leave the coop door open for air flow. I live in NY so the hottest summers I’ve seen were around 100 tops rarely. The whole coop and run is surrounded by hardware cloth on all sides and on top too so predators shouldnt be an issue if i leave the door open

When you can leave the front open, that'll help a lot. The ventilation is actually more important in the winter than the summer. The heat and humidity the chickens put off can freeze easier and cause frostbite in the winter without enough ventilation. It also leads to respiratory issues.
My coop is a large, plastic type shed, so I couldn't easily add more windows either. I bought a small outdoor fan and mounted it up high. It's a good way to get enough ventilation without more windows. If you have electric to your coop I can send you a link to the one I use. It's adjustable, so you can turn it up in the summer, but when it's cold, it still moves enough air without being drafty.

I may try the fan idea. I currently dont have electricity at the coop yet may add it soon tho.
