:/Thelma Lou has been setting now for 8 weeks! The eggs she was originally setting on either disappeared 1 by 1 or somehow got busted (by Thelma Lou?--I know for sure she busted 1 herself.) She continued to set on that last egg until she'd been setting almost 5 weeks, then it too disappeared. She continued to set on an empty nest until last week when I put 2 eggs from the other hens under her, figuring if she's going to set, she might as well have some eggs to set on in case we can get babies. Then yesterday I was told I should not let her set that long because she'll go blind. Is that true? Any advice at all will be appreciated, since I've only had chickens a few years and don't know much more than when I started.
