I'm designing my future coop for my 5 chickens tonight and I wanted some advice about where to put the vents and how many? I could put doors on it so they can close in the winter if that is best. Also, I was wondering if I even need more than one? Is it best to put them near the roof because heat rises or is it okay if it's near where they pirch? Also, is it good to have them on opposite walls for circulation? Does that matter? *sigh*! What if i just had a wood floor and a wall that opened so I could sweep it out every week or so? Would it be best if I just had a wire floor for it all to fall through? ONE more thing! What are the benefits of the coop being movable? Is it bad if it's not? It might be easier if I don't have to move it all over the place. More stress! Why can't there just be a chicken coop builder around here? Ah well! Guess I AM the chicken coop builder!
