Oversize auto chicken door

[proudpiggyfarm]

Hi!
For months I have been looking for an automatic timed coop door that locks. Problem is, I need it to be oversized. Our mini pigs and mini goats and turkeys use it as well. our current door is 15"x23". Before I gave up I thought I would try asking here. I can't be the only one who needs an oversized auto door!

Maybe look into dog doors?

I have never used an automatic whatever.

Did you ever find one?
Are you a tinker-er?
Maybe you can attach the motor/ hardware to a custom door?
