Out of 12 eggs that went in the incubator on day 18, only 3 pipped. One hatched by itself and the other two I helped out on day 23, two full days after they pipped. All three were sticky, and the two I helped out would never have made it out on their own. Their heads were stuck to their bodies. I washed them and put them back in the bator. One of them wasn't doing good at all, has curled up feet and even when we made boots for him out of tape, he still falls on his face. He has pasty butt and looks like he has some other things wrong with him. I will probably put him down in the morning. The first chick that hatched has a foot problem too but it corrected itself. The last chick only had one curled up foot and we put a boot on it, but it fell in the waterer and drowned. So can someone give me suggestions on how to avoid sticky chicks and curled feet?
