Dog sneaking into the coop

[CrispChooks]

We have a Labrador who we’ve caught sneaking into the coop to steal eggs. The girls free range during the day and are locked up at night. During the day, we’ve caught the dog sneaking into the coop to chomp the eggs. How can we allow access to the nest boxes for the hens but keep the ever hungry Labrador out?
We didn’t think it were possible for her to fit through the chicken door. Please see attached chicken door and the forever hungry Labrador

Can you add baffles to the door? A milk crate with a hole sawn in it? A board mounted across?

Is the dog also outside all day?

She’s inside and outside as she pleases.

I’ll try the milk crate suggestion, it won’t make the hole smaller but may deter the dog. I can’t add baffles, or the biggest of the chooks won’t fit

They'll fit, add a board back hight to the tallest one or make an upside down V to not allow puppers shoulders

Install roll-away nest boxes where the eggs will be collected out of reach of chickens, dogs and even smart magpies, squirrels etc. if you install a lid.
