1) what kind of chicken do I buy?
Oh my, this is a wide open question! I have tried lots of different breeds in my small flock, and I can only tell you my favorites. I used to think my Barred Plymouth Rocks were my favorites as far as friendliness goes, but then I got some Buff Orpingtons and they are soo sweet. BUT, then I added a couple of Rhode Island Whites (not the same breed as the Reds) and these guys are currently my favorites for friendliness and daily laying ability. I do think they're a lot more difficult to find than the rocks and the orpingtons, though.
2) must i get them as babies if i intend to handle them as an adult?
I used to think so, but now I don't. My last 6 chickens I bought as unhandled 4 month old pullets, and they are the friendliest of the bunch, even moreso than those I raised from chicks. Once they know you're the scratch/kitchen scrap/worm deliverer, you'll be their best friend. My RIWhites actually jump up on stuff to be closer to me all the time, so I can even hold and pet them, unlike most of the others.
3) do i have to have a rooster if i want eggs?
No rooster needed, and with just the few hens you want, it would be too much 'loving'. Skip the roo.
4) what is the average lifespan of a chicken?
I hear people say that they have some go 10 years, but I don't seem to be able to keep them much longer than 6. The unfortunate thing about chickens is that sometimes they just die, and sometimes there are illness you have to deal with. Infectious coryza wiped out 1/2 my flock a couple of years ago, and it was heartbreaking. It did, however, allow me to get new, younger birds. I guess the moral of this message is that you'll grow attached to them, and sometimes they die. Ugh.
5) is two chickens enough for eggs for two people?
Two is good, but I think three or four would be better. Kind of depends on the size of your chicken tractor, too. I see a ton of different designs for chicken tractors being sold on Craig's List, so make sure to look there too for ideas. You might also want to consider, depending on your climate, how you would run electricity to it if you think you might need a heat lamp or even a water heater (to keep the water from freezing). It's just the two of us too, but I have 13 hens because I love them and love giving the eggs away. During the winter we barely get enough eggs to keep us going (plus I'm baking a lot during that time, too) but now I get 8-9 a day so I give a lot away too. Don't forget that eggs are great protein, so if you have a bit more than you think you need, you'll start making quiche and frittata's more frequently in place of other proteins that you would have bought. Also, there is no correlation with the cholesterol you eat and what builds up in your arteries, so don't worry about upping your egg consumption.
If you can think of any other information that I need, feel free to pass it along. I am just starting my research now.
Frankly, I love keeping chickens so much, I find it hard to believe that more people don't get involved if they have the space, time and their neighborhood allows it. The city of Seattle even allows a few hens (no roos) and many communities are rethinking the value of having a few backyard hens. They (chickens) are also great recyclers, eating most of my kitchen scraps so I now have very little organic waste (I don't feed things that come from onions, avacados, potato peels (all supposed to be bad for them) and citrus as they don't like it.)
Quite a few of us have chickens here and love to talk about them, so please feel free to ask questions. You might also search for chicken on this site and see what else we've talked about. Have fun doing your research! ~jayne
