The last 4 eggs have still done nothing and it is day 22. Poor little "Uno" is the only little cochin all by himself in the brooder. He pipped and zipped so quickly on Day 20 I thought the rest would follow. all had movement when they went in the hatcher. My temps did drop a little (to 99 from 100.5) the last couple of nights. Now the humidity is dropping also, down to 63. I had to take him out and did so very quickly last night, have not opened the bator but that one time since they went in. Should I quickly add more water? How long should I wait before I give up completely? Poor Uno is so little he can't go in with the other chicks, I may need to findhim a day old buddy somewhere. He is certainly lively though and doing all the normal chick things, also very attached to me and hubby, he climbs in your hand when you put it in the brooder.
