My chickens got out because SOMEBODY left the gate open. OK, I admit, it was me. They got into the front yard, not only on to the chemically treated lawn, but also to a dead bird. The cat brought us a lovely dead wild bird present yesterday morning and as it was my son's cat, I was going to make him clean it up after school. I put two and two together this morning when my son told me the birds got out last night while we were all out and later realized the dead bird has vanished. Does this make my chickens, who obviously devoured the poor bird, likely to get some type of worms? Should I treat them as a precaution or not worry about it?
