Hi everyone, I've just joined but have been on here loads and prob been saved a couple of times. About last year I started to hatch chicks as I noticed the cupboard next to the aga was fairly warm and keeps around 37 pretty well, I got a fairly good hatch so have done it a couple more times. I know this is fairly dodgy as temps and humidity can be pretty vague but it seems to work. Any hoo, I put a double yolker in with my last batch and Its made it this far, It will be day 19 tomo middayish, Just checked them and shining a torch at the air sac i can see movement. I have read a load of threads but still unsure on whats best to do. I have heard of people helping out on day 19 by pipping the air sac but im tempted to wait a bit longer before jumping in. What do you guys think??
