I need help with some chicken math, but not THAT kind of chicken math I'll be getting my first chickens next spring, building the coop now. I want to hatch them from eggs though. So I'm trying to figure out how many hatching eggs I need to order, how to factor in various risk factors, so that I can arrive at a target number of chickens. The things I can think of so far to factor in are: - Some eggs may break during shipping - Some eggs may not hatch - Some chicks may die young - Some will be roosters I'm aiming for 3 hens and 1 rooster as the final flock. I know that there's a wide range of possible outcomes on any of those points... If I order 12 eggs I may end up with 12 chickens, or I may end up with 2... and pretty much any ratio of males to females... But still, can you guys give me some rough numbers to start with? How many eggs should I order? What's the rough likelihood of any of the above issues happening? (like, is it common for chicks to die young if you care for them well... etc.) I'll be ordering my eggs from Papa's Poultry, and he has a good track record of egg fertility and packing eggs well to prevent breakage, and sending extras. Also, being that I will likely temporarily have more chickens than I aim for, exceeding the capacity of my coop, is it okay to start out with more, until I narrow it down to the target flock size (after finding out which are roosters), given that they'll be smaller when young so hopefully won't feel too packed...? My coop will be able to hold 8-9 full-size birds. I'll be getting orpingtons. Thanks!
