I have 2 hens that seem to have lost weight. One is still laying and the other has stopped (she's about 18 months). The one who is laying was attacked by a dog in March, and nearly died (hunks of flesh were missing). I put her in the "chicken hospital" inside and she survived - so the fact that she is skinny is logical. She happens to be the one who is laying - RIR. Got a huge double-yolker from her yesterday. When I pulled the straw out of the coop this spring, I left it in the run, but after reading some stuff I realized how bad this is since they're probably eating their poo, and combined with a very rainy spring, I think they might have parasites. What do I do? We're going to have rain for the next week!!
