I was given 2 stryo bators last year. Used. I hatched in Hovabators in prior years that I borrowed from 4-H and had great hatch rates. Since I have used these two, 3 hatches last year and one this year, the results are awful. The chicks that hatch are slow to thrive and then I have chicks that pip and greenish fluid comes out and then they die. Needless to say these are in the trash and I have ordered 2 new Brinsea Eco's. Does anyone know if there is a bacteria or virus in the styrofoam that dosen/t die when I sanitize with bleach. A week or so prior to hatch I put them in the tub with hot water and bleach to clean and use a paper towel in the solution and wipe down everything else.
