So far I haven't lost one yet. I did see a orange tabby roaming my 3 fenced acres. Hopefully the dog did her thing with it. a week ago I put the 6 RIR's out in the coop area. Today I put the 6 BO's out there too. The 3 Redstars are still in the brooder. I gave them a few hours out with the others earlier today. They seemed to enjoy it once they figured out where they were and had 12 big sisters around.
