I have lost 2 of my polish chicks. The first one was 1 week old (died last week) and the second one was 2 weeks old (died yesterday morning). Both chicks seemed healthy, were eating and drinking, acting normal. I went to bed and when I got up the next morning they were dead (first one last week and second one yesterday morning). The first chick had nothing abnormal about it, but the second chicks abdomen was wet. There was a small amount of pinkish colored poop coming out the vent and the feathers surrounding the vent (about the size of a quarter) were damp. The poop did not look bloody, just pinkish. Prior to the deaths, both chicks had normal poop. I have never had Polish chickens before. I recently got 3 polish chicks and 3 houdan chicks. All 3 houdans are doing fine and the other polish seems to be doing fine also. The 2 lost were buff laced polish and the one surviving is a silver laced polish. The chicks were in a brooder in the house. The brooder is covered. There are 4 frizzle chicks in with them also, all healthy and doing fine. All chicks are 2 weeks or less. There couldn't have been any injuries. I'm at a loss as to what happened to them. Any ideas?
