Will be raising chickens next spring.
If you want to raise chickens and have a farm to do it then you at least have 1 point on you. The difficulty of raising chickens would depend on how many you want to care for in any given time. The more the dirtier. They poop all the time and you have to feed and give them water all the time. So this means you have to clean their cages all time to avoid any diseases and to avoid neighbors complaining how smelly your surrounding area is.
If you plan to sell them, there are chicks sold that you will need to raise within 45 days anything over 45 days the chicken tends to develop very hard and stiff meat that people of course wouldn't want to eat.
Also if you are planning to hatch the actual eggs then grow them the mortality rate is like 50%. You need to incubate them accordingly and you have to care for them more. but if you plan to raise chickens for pets and would only have like 3 chicks at time, it will be less work of course. However they constantly need heat whether it is summer or not. they need like a light bulb in their cage every night that is cool.
We use to raise chickens as both pets and for business. We gave up after 2 months because it was just too hard for us. We kept 3 chickens as pets and they grew to be around 20 lbs each. They could hardly walk or run. They looked funny but of course they didn't last long. Just like any living thing too much of everything is bad. I thought maybe one died of a heart attack. Cheers!
