I have ALWAYS had problems with muscovy eggs turning blue/black. Today I had to throw out 8. I was trying to wait till I had an incubator full before I set it so they were out on my bathroom counter top in a shoe box for 2 weeks from hatch till blue. The ones I threw out did NOT pass the sniff...
I have a Brower's like the one seen here ------> https://www.backyardchickens.com/t/626281/anyone-use-a-brower-incubator . Does anyone know where I can find replacement parts for it? I need the particle board insulation, the plastic window, and maybe another part or two.
