Hi aliceb---
You are smart to get chickens. everyone should have them.
The same concerns that you expressed passed through my mind..and I am brand new to chickens. I think that your idea of two or three is a good starting point... (I have 3). It occurs to me that it doesn't take much more work to take care of a flock than it takes to care for a cat. There are some caveats and variables... Some chickens are noiser than other breeds.... just like some cats are noisier.
Your chickens will be noisiest when they see you coming around, because they will begin to associate you with food, and treats.....
I researched coop options, and I ended up getting an 'Eglu Go' and attached run. It is like a small dog house... The back opens like an oven, and the floor slides out completely. So once I had the set up and routine down, it was less than 5-minutes each day.
1. Put in fresh feed, they run to gobble it up, ( I do take feed in every night so no mice think it is a buffet awaiting them)
2. Close the door to the run, so they won't stroll out of the back of the coop while I am dumping
3. open the back door
4. pull out the bottom
5. dump the poo and wood shavings in a plastic container that holds it until convenient to put in compost,
6. If it is sloppy/dirty, squirt with a hose and brush with a car-wash brush or dish brush ---make sure it is dry before adding wood shavings.
7. put fresh wood shavings on floor and in the nest box area.
8. Then slide the floor and nest-box/ roosts in close up the back door, and open the pop door---- just in time for the egg laying to begin.
9. Make certain the waterer is clean and topped off
That takes longer to write (and read) than to do.
After that -- refresh the water, and by 9:00 we usually have the first of 3 eggs. I am astonished and in awe of how productive these chickens are.
Once a week if needed a little more washing like on the detachable back door for example, may be worthwhile.
I have three huge tubs that cattle molasses supplement comes in. One for poop, one for shavings, scrub brush, scooper and DE and one for feed, grit, oyster shells and treats. Each has a snap on lid and makes for a great seat to sit and watch the chicken antics.
because the Eglu is plastic, it doesn't need repainting, or treating, mites can't get into the perches etc.. Wood coops are reputed to need annual painting or finishing on the inside.... Probably a lot of that depends upon climate and exposure.
I think that from what I have read on this forum, the owner of a few chickens can clean daily -- and the owners of many chickens clean the coops, yearly or half-yearly. It could be that the time commitment is nearly the same.
Where you live will influence what works best for you. If predator protection is important, be sure to factor that into your planning. The person who suggested a chicken tractor provided good advice, moving the coop around can be very advantageous.
A downside to the Eglu Go is that it is very low-to-the ground. So maybe if you get something like an Eglu, or if you get a chicken-tractor like an A-frame you may want to be sure that you can easily access it when you are pregnant. (Or if you keep chickens a very long, long, long time, when you get old and arthritic like me. :O) )
Hopefully your husband will become as enthusiastic about chickens as you will be. We love our chickens!
Think through your criteria and once you have determined what will work for your needs, you will be on your way to flock happiness.
