If using a different RPi that does have POE on board, i can do that... but will POE alone have enough power to run the door motor or am still looking at a battery, etc...
First off, you need to test your system at Full Operation and at Normal Operation. You need to know how many Amps/Watts you will be drawing. There are many videos on youtube.
POE operation greatly depends on How and what equipment you are using. POE just means Power Over Ethernet CABLE. So to answer your question, "will POE alone have enough power to run the door motor": That depends on how and what you plan to use.
If you use your computer Ethernet Module and have a seperate Power sources that will support that motor, then you send receive data and power through cat5, then yes it can work.
If you use a dedicated Switch managed or unmanaged with POE capabilities. Then yes, if the Switch has the rated power output. Some are only rated at around 30W per port and will only support small pan/tilt and bullet cameras, while other more expensive switches are 60W per port and can support larger pan/tilt cameras.
This is the one I would and will be putting in my next coop, when I get around to building it.

If you don't have AC power run to your coop the I suggest that you have a battery setup. If you will be running a RPi, Switch and cameras then you will need at least two good quality batteries and a charger to maintain. Really, having cameras run from the coop is an expensive undertaking if you want good quality video and capabilities.
Right now, in the morning, the girls door is being opened by a string on the door, and at the end of the day, door closed by an opposite string...but when at my job, I want to be able to pull out my phone, and check on them (cameras) remotely...
If you want to automate the door. By looking at the pictures you provided, it looks like you could do what his guy did. I like how he did it. His is done with a gear box and 3D printed stuff but you can do the same with a car power window motor (already has the gearbox and spool) and cables. If you need help with the wiring just post the pics of the parts you have or links to what you might buy and I will get a diagram together.
You can control it with one of these.

Yes I did look at that post... I did miss where the muffler bearing went, and where the flux capacitor was hooked up....
@Mouthpear must be an electrical engineer...which I AM NOT...
"I did miss where the muffler bearing went, and where the flux capacitator was hooked up..." I am going to take this as a friendly jab rather than a demeaning mocking. It could go either way. In any case I try and give as much information but try to keep the TASK itself as simple and economical as possible.
must be an electrical engineer...which I AM NOT...
I'm not either. LOL
In the army my MOS was 31U Signal Systems Support Specialists.
I have degrees in computer networking.
But I work as a carpenter foreman for a large general contractor when they have projects here.
In the meantime I weld and work for a buddy of mine as a welder's helper.
So all this may sound weird but when I tell you I am a medically retired disabled Veteran it might make more sense.
