I have a hovabator/turner/fan. I am having a HORRIBLE time with humidity! Been getting bad-footed chicks, yesterday a splay leg chick. Taped her feet & seems better. Also lousy hatch rate. For 3 weeks I fight to keep up humidity. Never had this problem when I 1st started hatching. Day 22 I got 1 chick & 1 pipping. Any ideas? I put in sponge but is seems as soon as humidity is up, it drops like a rock. I was gone 12 hours and it had dropped to 16! Hate to waste eggs. Last hatch was 19 out of 38! Anybody?
