What temperatures are right for your hens? What happens when temperatures are too high? What happens when they’re too low? This infographic shows you the effect of air temperatures on laying hens.
This infographic comes from Poultry Production: The Practice and Science of Chickens by Leslie E. Card, which I have reprinted under my Norton Creek Press label. It has hundreds and hundreds of pages of useful information like this. Like most of the really useful poultry books, this one was first published a while ago, in 1961. But it’s a gold mine in spite of (because of?) this.
