Switched my girls to FF. gave it to them the first time monday about 3 hours before I put them to bed. They didn't touch it before bedtime. Got home from work yesterday and they had destroyed it. Gave them some more and they tore into it as soon as I put the bowl down. So happy they are eating it and liking it, as its better for them and cheaper for me. They just turned 5 weeks monday, already planning on adding 10 more girls to the 8 I have. Got a couple of friends coming over to help me work on the coop next week, but I'm going to be busting my butt on it in the meantime. Got the materials, have a solid design in my head for everything but the run and the nest box. I'm gonna go with a community box, just not sure how big it needs to be for 18 hens. (hope I end up with 18, still not sure I don't have roo's).
