I am new to all this and I have a question about making a giant hood. The giant hoods I see seem to be heavy and I was wondering if you can use canvas double layered for the sides, front and back which would cut down a lot on weight. Would this let too much light in or would this be a problem if the birds grab the canvas? Just thinking out loud. I raise homing pigeons and I know you do not need to worry about talons and beaks but on all my boxes the side are canvas and it cuts down tremendously on weight and injuries. No laughing was just wondering.
