I never saw this post! I think there’s always a risk, sadly.... no matter how much you predator proof. But it sounds like your setup is really solid. If a raccoon wants to, it can get into most things. I have raccoons where I live but they have not yet visited since I set up my coop and run this Fall. I leave my window cracked so I can hear visitors in the night. So far just one feral cats and one rat that I e seen. Both were annoyed there was no obvious entryway. I ordered one of those auto doors and am going to install this weekend. I’ve done the same as you and opened the coop door to the run before sunrise. So far so good. I want to install some cameras in 2020! I’ll send protective wishes for your chickens! City life is rough!!Thoughts requested on my SW Portland coop (near Burlingame Fredmeyer). It has a closed in run. Closed with metal cloth all around and even under the run. I have been rather negligent of late in closing the coop door that leads to the run as I leave the house before the sun is out and i don't have electricity at the coop for automatic openers. So generally I have been leaving that door open and I check on them as soon as I get home. Am I running too much of a risk with predator risk?
