I have read many different "calculations" on how to figure how many nest boxes you need per how many laying hens. They vary from 1:3 to 1:8. I have 42 chicks. Most of which are pullets. There are only 5 that are st run so I am not sure on those and there in the possibility of error on sexing from the hatchery, but otherwise, I will have in the vicinity of 40 laying hens. I am trying to figure out how many nest boxes I need. I don't want to build 40 nest boxes if they aren't needed, but I don't want to build 10 and need 20. Can anyone give me a "real life" number of nest boxes that I will need for this many hens? Your help is great ly appreciated. Thank you.
