Customer Service is amazing! I have the Omlette Eglu coop, attached run, walk-in run and all the accessories. I've had to contact them many times and they are so helpful and accommodating. Usually it's a British person either in NY or the UK that answers.
Hi. I have an Omlet auto door on an Eglu Cube coop. I love the auto door. To give you a visual (see pics). My 4 girls are 8-month old standard sized breeds. I can't imagine any chicken (even a big roo) wouldn't be able to get through 😁
