I have a hen separated from the group (she was attacked by a hawk, broke her leg and is in recovery). She's been isolated for at least a week. We took her outside yesterday to walk around in her reduced "cast" which she thoroughly enjoyed (no idea if this relates, but i thought i'd toss it in just in case). The following morning, she laid an egg. She hasn't been consistent in her egg laying since the incident. We get one about every third day lately. This egg, though, was covered in a powder or dust of some sort. Now, normally our girls lay eggs with small bumps on the shell and maybe a very thin pale coating (which you can only tell exists if they scratched some of it off with their nails), but this egg had chunks of this powder stuck to the sides. It washed off as though someone had just stuck flour to it somehow, but I'm worried it means she's not okay. I know sometimes they just lay weird eggs, but I still thought I'd check if this was an indicator of anything. I couldn't find anything online about it. So, final questions: is the bird sick (if so, with what) and is the egg still edible? thanks!
