I might have to fix the ventalation in my coop...

Coop ventilation is very important, more is better!
Here's a good article on ventilation: http://www.backyardchickens.com/a/c...-go-out-there-and-cut-more-holes-in-your-coop
If you need someone to help you figure out where your coop needs more or how to do it, there's a lot of knowledgeable folks on the coop/run forums - you could post photos and ask for ideas https://www.backyardchickens.com/forums/coop-run-design-construction-maintenance.9/

I would think they are pecking/pulling at each other during roosting. If you haven't done so, consider offering more space when you can.

Can I ask, how much ventilation you have in your current coop? Do you have any windows or vents that you can open. As temperatures rise, I can see that they would get too warm in that small of a space - I see you are in Texas, so I assume you have hot summers.

This one is pretty ventilated, the ridge of the roof and where the roof meets the walls are all open. And it’s got 4 big vent holes on the side you can’t see. But it’s only temporary, thankfully. Another week or two and our big coop will be done for them to move into. I definitely think Pebbles, the feisty ameracauna, picks fights to sleep on the doorway ledge. She’s the only one I ever see taking up the whole doorway space. Go figure she’s the smallest of them, too.
