The plans for the coop were free, published with step by step instructions in a library book.
The first trip to the home improvement big box store cost about $170, and we thought we had pretty much everything for the coop and the run would be inconsequential in comparison, ha! The lumber we purchased did build the coop, but it seemed that we needed more hardware. Off to the local hardware store for screws of a different diameter or length, latches for the doors, hardware cloth, chicken wire, poultry staples for attaching chicken wire (really if you go into the hardware section they have a box labelled poultry staples), corner braces, you name it. Oh, and then exterior paint had to be chosen (by my daughter) and purchased. The woman mixing the paint exclaimed that the chicks and ducks will think they have been transported to the Caribbean, so be warned. Next more hardware and then even more hardware. For the last thirty dollars of hardware they gave us an itty bitty bag and as if to make up for the size of the bag, they threw in a bumper sticker that said "United We Stand". Sigh.
The benefits for our several hundred dollar investment we will get some of the yummiest eggs available, I don't want to calculate the value of each eggs the girls produce, it would be laughable (or cry-able). The girls (and Sebastian) are really pets, so they have their little penthouse, where they slept for the first time last night, Our garage seems lonely. No nameless boy chicks scurrying about, no Kiwi and Sunny running up to me to seeking some attention, no ducks soaking up rays from the heat lamp with the, "Hey, what's up!" look as I come down the steps. It smells better in there already.
There was a throng of excitement as I opened the coop door to put in breakfast this morning, it was intense. Today their ramp to the outside will be built and they will be able to enter and leave as they wish. What is now their prison will really be their penthouse.
So to answer my initial question--I don't want to know and I will not add it up. I will enjoy the antics of the girls and Sebastian, and savor the eggs produced. It will be worth it in the end.
