WOW more ways to incorperate into my quail pen. LOL
You always have some great ideas.
I don't understand why you go under attack though. You have great things to share here, for those who need help and some cheap and easy alternatives. Not every situation is the same and some people will have to find another solution to a problem. You have been offering several, so I'm going to offer to be one of your "buddys" and say Thank You!
My nest boxes are low. The roost is nowhere near the boxes and I get poop in them. Not a lot, but I don't like it. I also have a hen that delivers to the back door. Sometimes I find a slightly cracked egg on the cement, so I don't think the extra padding in the nest box is a must to them. My boxes are filled and most of the times I'm tossing away what a put in. I have a few girls that work all the way to the wood on the bottom to lay. They waste so much bedding it's not funny.
I don't think your boxes are a bad idea at all. The idea is, go in, lay an egg and get out. Less time in should mean less chance to poop in them too. The only thing I had a question about though is the 10" for the roll out. Is that kind of far and do you ever have a problem with eggs cracking when they bump eachother? I'm just asking, because I was thinking of making them 1-3" shorter and was wonder what you thought.
BTW I also have a hen, that if she hasn't laid before she's running the yard, will fly up on top of a rabbit cage to lay her egg. It's made of wire. Yes I have some strange birds.
