You'll probably find a million ways for a second chicken coop to help your flock. Just knowing you have one can put your mind at ease. If you want to be very cunning and use a good Chicken Math, this is the time when you can upgrade to a larger chicken coop so you can have a larger flock. The main reason chicken coops have two doors is quite simple.
There is a door that acts as an entrance for chickens to enter and leave their shelter. They will understand which door is intended for this purpose and will know how to go there. Unlike urban chicken, you can make the most of your herd when you have it in the chicken yard. Those eggs need a safe and warm space to grow safely and the chicken coop offers just that to both the hen and the egg.
However, common sense is very useful for raising chickens, but having a great resource to look up things and ask questions has really taught me more than I ever thought I could. Barbara H. Maybe you could have a hat made with a comb on it and profess your wisdom from the top of a chicken stroke. The only thing I would have liked to know before having chickens in the backyard is how to plan for the future.
I struggled for a long time to keep the chickens contained before discovering that chickens don't fly and perch on a wobbly fence (they need to feel that they can safely land on top of it and then they can jump). It's also cheaper and easier to enclose a large area that way, so now my chickens have a huge yard of their own. Seriously though, a diverse flock of chickens in the backyard is not only a delight, but it is quite advantageous in several ways. Think about how scary it must be for a chicken to see a human being trying to get into its little domain.
I can't believe anyone mentioned this, make sure you have people lined up to serve as a chicken for you. Some might recommend that having just two chickens is OK, but one should never have fewer than three to meet the social needs of birds. Unfortunately, chickens can contract diseases that show no obvious symptoms until the disease has progressed to the point where it is too late to treat the bird or there is simply no treatment. This means making sure that the chicken coop is well ventilated and also safe from predators and has enough square feet per chicken.
