You’re right. I haven’t made compost in about 40 years. I see there is a lot of info about it on the web. If you put in the right mix, moisten it, then let it heat up to extremely hot temps, and then stir it and repeat at least twice more, you can use it a lot sooner. Still should sit about 120 days to let all the pathogens die out. Chicken poop is loaded with salmonella and such.
