I could really use some advice/help. This has never happened to me and is confusing. I had some chicks to hatch Thursday. 2 zipped when I was leaving for a couple hours. Came home and that had not changed and I heard not chirping. Took them out and both where DIS. Today....Very same thing happened. They are completely zipped but never push out of the egg. My temp is 99 and the humidity is running between 55-60. This is really confusing to me. I don't know what to do. Thanks so much!!
