I have 5 biels and 3 niederrhieners (similar type of pig) plus a brahma and EE (10) with at least 7 laying. They can’t forage now so #50 lb of 17% all flock pellet lasts 3-3.5 weeks. I also give 1/3 lb sprout barley every day-ever other day in winter. (2-3ft snow on ground right now). In summer most free ranged very well all day and my feed lasted 6 weeks minimum. The roosters are great attendants. I can’t speak to how well roos are against predators bc I’ve been luck not to have losses yet.I have a feeding question. I've heard that Bs eat a lot. How much would a small flock of 7-8 eat in a month? My flock of 7 (no Bs in it) go through 50 pounds of all flock in about a month. I have 6 hens (Australorps and Orpington) and 1 Chantecler rooster.
ETA: I think they consume more in the first 6-7 months then level out, IMO
