Rob, scary thoughts about the Ambassador.
Brent, it will be spacious for my 4, and house 6 easily, maybe a few more. Figure 4 square feet per full sized bird. The coop depending on how you think of it is either 4 x 6 or 5 x 6. The extra foot is for some nest boxes in that front area with the downward framing.
Young healthy layers put out about an egg every 25 hours. Another way of estimating is 2 eggs every 3 days per bird. In any case, eggs have received a bum rap, in my opinion, in that they have low saturated fat, and lots of good things, as well as cholesterol. I eat them freely, and my cholesterol numbers are ok. So how many eggs a week? Well I don't keep track really. We typically get 2 - 4 eggs a day. We have 2 dozen in the fridge right now, and eat all we like, and give the occasional surplus to our friends. When we got started, I thought we should get 6 birds, but LOML thought 4 would give us all the eggs we need. She was right [again.] Hens lay well for about 3 years. After that, numbers and quality goes down. Our hens have been laying since September, so we have a while to go before they retire. Brent, if you're thinking you'd like chickens, chances are good you will. It really is fun. Heck, even building the coop is fun.
