Cuterabra... is that what people used to call a "screw worm?" I remember my sister's rabbit having one when we were kids.
Didn't get to bed till almost 5:00a.m. so I just got up. Holy cow! It's got to be 115 degrees already! I've got to mow the grass today, but it's still wet. It's going to be one hot job, that's for sure. All the rain we had this past week has really brought on the grass and weeds.
Hawkeye, I wish I could give you a little better idea about what to do for vents. I'm still trying to figure that one out myself. We are up on a hill, and sometimes the wind blows so hard that the snow and the rain can blow into anything from the side. I think whatever you put in just be sure it can seal off well from the rain or blowing snow. One of the last things you want is moisture in the coop. They do need ventilation for sure. Maybe it would be a good time to go browse the salvage places and second had building materials to see just what is available.
I think for myself, I'm going to try to find a big fan and vent unit, almost like what a greenhouse would use. I want to be able to close it off well for the winter, so we will see what I can find. I'm thinking a large vent on one end and a fan/vent on the other end of the building would work pretty good, almost like a "whole house fan."
