Just say no.
Chickens are a PITA. I said no for two years, eventually said yes because the youngest and wife wanted the chickens and constantly hen pecked me. It was fun for about a year but then letting the chickens out in the morning, giving them food and water, bringing in the eggs, cleaning stuff from time to time, chasing them down and putting them back in the run when the escaped, and at night locking them in the coop got old.
The hens were fun to watch, the lady at the community college called watching them Chicken TV. One of the hens was like a dog, was super friendly and would follow us around. Of course that was was bullied and hen pecked by the head hen, got sick and died.

That head bully hen then started on other hens and we gave her away. I wanted to eat her but it was not allowed.

Another hen got taken by a fox when they flock got out of the run. With three hens we were not getting enough eggs to be worth it.
At the time, chicken feed did not cost chicken feed. We were buying some expensive feed because it had a better mix of grains/seeds than the cheaper brand. When we tried the cheaper brand, we got less eggs. Bottom line, is that we could buy the better brands of eggs in the store cheaper then buying chicken feed. I eat eggs almost every day and I did not taste the difference in our eggs vs the good store brands. Also you have to buy them grit which is just and added expense and when it is cold out we would run a heat lamp for them.
For me, the biggest PITA was having to pay for someone to check on the chickens when we went on vacation. One person did not even show up and which almost killed the chickens.
Save yourself some time and money and stay away from chickens. Maybe it would be different if she will let you eat the hens when they get old but I doubt she will....
A foster home took in the hens and we not longer have those PITAs. :cool2::cool2::cool2:
