Stocking up on Feed

A trip to the mill shop today to stock up on feed for the girls. More than doubling the flock size will more than double the food requirement, so I bought 3 sacks of layers pellets and 1 sack of layers mash. We need to understand how much feed we’ll need when we increase the number of hens we keep, and whilst a hen should eat about 120 grams of pellets per day, we’re going to start a 20kg bag of feed on Monday and see how long this lasts for 21 hens.
