This is the last of my Houdan chicks, had 3, already lost two. Those two showed no signs or symptoms, just found them dead. One at 1 week and one at 5 weeks. Also had 3 Polish, lost one at 2 weeks and one at 4 weeks, one left. All from same breeder and in same brooder. This chick is 7 weeks old, appeared healthy until today. When I went to clean the brooder this morning, I noticed it falling over on its side, one leg pulled up to the abdomen, the other leg kicking out. Upon examaning the chick noticed on the abdomen an area about the size of a quarter, looks as though it was wet, the feathers are hard and dried to the skin. I am searching BYC but thought I would post so while I'm searching, perhaps someone would be able to help. Their brooder is kept very clean, fresh water and nonmedicated starter feed. I was using medicated feed at first, but others on BYC suggested nonmedicated feed after loosing previous chicks.
