One of my younger BSSP girls I found this morning in the corner of the coop with almost all her crest feathers picked out and her eye completely full of dried sand. I took her inside and held a warm wet paper towel on her eye for a few minutes and was able to rinse most of the sand out (there's still just a little bit still stuck to her lower eyelid now). I had to put her back in with the others because the farrier (person who trims horses' feet) was here and I had to get the horses. After the farrier left I went straight to the pea house to check on her, she was back in the same corner, sitting very still, with no more crest feathers on her head. I have her inside with me now, and I plan on giving her her own space in the brooder box in my living room. I have her with me while the heat lamp warms up. I have vitamin and electrolyte stuff that I can put in her water, I also have Corid, but don't know if this is the right circumstance to use it. What should I do? She's very lethargic... Thanks everyone.
