My assorted bantams from Tractor Supply were hatched last Monday. I purchased them on Sunday, March 27. I have lost 2 of my 4 chicks. They are eating well. They seem to be very comfortable with the temperature. No crowding around the lamp or pushing against the edges of the brooder. They are drinking water. I know one was weak when I brought it home, but I was shocked to find another baby passed away around noon today. I just don't know what to do. Maybe more protein. If so how do I get them to eat the yogurt. They are not interested in it at all. Please see pics below of my brooder and let me know if anything looks crazy out of line, like a baby chick killer.
