Well my 133 bobs are hatching away. More and more as i get back to look into the incubator. I have about 50 or so iside my plastic playmate 50Gal box. For floor cover im using bedding straw. Ive read that pine shavings are bad. Ive used them before years back but im just starting to hatch birds again. I know i dont want cedar but whats wrong with plan pine shavings? Pros and cons anyone? What do you use for the bottom of your brooder?
