I built this coop from recycled fence that a freind gave me. Total cost of the coop was $ 350.00. Casa de Huevos is a three sided coop. DDawn recomended this type of coop to me because of the extreme heat in Texas. The coop will house 25 hens which will be from my stock. The coop has a 5 gallon water-er which is the only item I did not build myself. I built the entire coop myself. Yes, I'm proud LOL. The coop has 2 roosts, 7 nesting box's, & a 100lb wood feeder. The coop is 330 sq feet. Personally, I dont' use the 4 foot, 10 foot rule. I think they need alot more space to live in. Thats just me though. I did tell yall a lie. You will never be finished building a coop I still have to make a sign for the coop.
