I had 10 runners from Holderread's. I lost 3 last Saturday. Then I just went out to feed and water everyone, 1 more dead. They are a month old in a 4X8x4 with 1/2 hardware wire all the way around brooder pen outside. They have a big pan of water and plenty of feed. They are on flock raiser with a mix of rolled oats, and cheerios. I give them grass clippings everyday. The dead ones have no marks on them that I can find, Every body looks and acts normal although they are in that don't touch me stage right now.
