I went on Craigslist and found a person selling and wanting to trade some chicks. I ended up bring home 5 lil ones. 2 blue silkies, 1 splash silkie, and 2 splash frizzle cochins. When I went to pick them up, I noticed the cages they were in were really really crowded. They didn't look very dirty surprisingly, but when I brought them home and started handling them, I noticed they are COVERED in crap. My husband had cut one HUGE chunk off one of the silkies legs but there are more, huge chunks like stuck to their legs, feet, wings. What should I do to help clean em up? Its just huge hard balls of poop all over them.
