I got three new Barred Rock chickens today. I believe they are 22 months old. They were from Craigslist. I know, I know... I was taking a chance on getting these. I have them separated from the others, of course. The previous owner said that they have a pecking problem. It seemed that where the chickens were they were just egg producers and not pets. They had a large run, but there was no grass at all. It was bare ground and nothing for them to do (no obstacles, nothing dangling, no perches, no dust baths, absolutely nothing. I also noticed that their feed trough was on the ground and not hanging (hence they had to bend over to eat and maybe someone pecked at them while they were eating or out of boredom.) The other chicken's behind is the same as these and there is a similar spot on her neck. I don't think it's mites or lice. I'm hoping a little TLC will do the trick. They have already been moved where there's a pecking piñata of cucumber. They have a Little Tikes picnic table and roof with a log. They have an old tire with new sand/gravel for a dust bath. I gave them oyster shells and a hanging feeder. I ordered some pinless peepers for them. Any extra tips or suggestions?
