Snake got one this sized, my only coral blue! After I got relocated the snake and patches the gaps, a black rat snake just like it showed up, looking for gaps...
I love your adorable pictures!!! Great creative and upcycled coop! The ventilation around the top is also a great idea for their health. However, I lost several 2 mo old keets to snakes in their coop. Do you have some hardware cloth that you could lay over the chicken wire?
