I lost the one chick that I had to help out of the shell, which I expected. However, I did NOT expect to lose another several days later! I think it may have been caused by an "herbal tonic" that I bought for the chicks as I have lost a few others with no health signs at all. I have more eggs in the incubator, but terribly worried that I won't end up with enough for breeding for meat next year. If anyone here sells chicks, please PM me...? Thanks!
