Just got six chicks - 2 barred rock, 2 americauna, 2 australorp. Beautiful! Our first time raising chickens. This morning (their first night here) I found one of the barred rocks with a bloody spot on its chest, covered by a wood shaving that is stuck to it. I searched but couldn't find anything on this particular pecking problem. I did find some shavings in their waterer, so I cleaned them out and elevated it. Their brooding area is about 30"x30" with a 250W red heat lamp off to one side; they don't seem to be huddling or running away from it, so I think they are properly heated. Do I need to add something for them to peck at? Should they have grit this young? Help much appreciated!
