hello all... so i built a chicken coop this past spring. it turned out great and i'm very happy with it, but i was rushed to get the chicks in it because they were out-growing their brooder. in my haste, i left out building the nest boxes that i really wanted. i want to build some external nest boxes before winter hits, but i'm having a tough time finding info on building them to an already existing coop. i'm no builder, but i think i could make it work with some good info. any pictures of your external nest boxes and how they are structured would be greatly appreciated. here are some pics of my coop right now. i'm thinking about putting the nest boxes off the left hand side of the coop in the first picture... like i said, any pictures or advice would be appreciated. i'm kinda worried about not making it strong enough to hold a couple of chickens plus the shingles on it and everything. also, i was originally thinking of having the roof of the boxes hinged to get eggs out, but now i'm leaning towards having the front hinged so i dont have to worry as much about water leaking through the hinge on top.
