I don't have chickens (illegal

) but I do have advice on incubating! I love to hatch them because it is so amazing to watch them hatch! They just pop out and it is very startling when all they have been doing for their whole life is sitting in their egg, just hanging out.
I have a little giant incubator with a (diy forced air) computer fan held up to the plexiglass panel with pipe-cleaners. It works
surprisingly well! There is no way I would buy another one if I could go back in time. I would just get a styrofoam cooler, square plexiglass window, and a heater and make it myself, because they are basically the same thing and it is considerably cheaper than the $40 styrofoam box

. I do enjoy that it was pre-built because the temperature regulation sounds intimidating to me, haha.
If you don't know already, you will have to turn the eggs if you are hatching them, so if you don't want to do that, you can look at an incubator with an egg turner. I made one myself, a little extra work but it was worth it! I only incubate a small number of eggs at a time (10-20ish), so I have the option to hand turn them, I'm not sure how many you are wanting.
Good luck with your new coop/chickens!!!
