I recently bought two 9300 still air Little Giant incubators for a few batches of eggs. One is working well and we have our first pip in one of the eggs this morning. However, the second one (which we set eggs in about a week ago and then 1 day ago) will not get warm enough. I have to set it at 102 degrees on the digital thermometer to get it to 97 degrees on the chick thermometer I put inside the incubator (which is accurate). I am hesitant to set it any higher than that even though the temperature should be at 99.5 degrees. The ones that are a week old are alive and moving inside the egg but I am so nervous because I keep thinking, what if it does start to work and goes up to the temperature it reads on the digital thermometer? At this point I want to just go get an incubator that is known to work well and has warranty (preferably life time). This would be the third time bringing this same incubator type back to the store in one week. The second time I went back to the farm store I did not have a pleasant experience. The man told me this has never happened before and that it was suspicious that I kept bringing them back. I don't understand this. I just want to keep them alive. I appreciate any advice anyone could give me. Thank you!
