I just hatched "incubator" 7 out of 16 copper marans sent from ebay. It was very exciting. I have 2 guineas that gave me 9 eggs that I put in along with the chicken eggs. I am reading that they should have been put in at a different temperature, and humidity. I have a incubator with a egg turner. Did I kill the guinea chicks? It is day 25 now?
Congrats on the chicks that did hatch! I am not sure about guineas as I have never hatched them. You might want to head over to our guinea section for some help with incubation...
