Well done for trying, its worth it. Chicks are amazing. I had a friend who binned what she thought was dud hatching eggs (they had been in the inch for 25 days) only to find one hatched in the wheelie bin. I think that with all of us getting so used to getting things being 'just right' with an incubator, faffing around with humidity, stressing over power cuts

etc etc we kind of forget that nature really has it's own way.
I currently have an orphan (mum would not accept it) house chicken. 6 wk old grower light Sussex. Barely alive when we found it out of the broody house, fluffed up but on wet grass lying flat. Mum still on the eggs. Popped chick under the grill. 20 mins later this little thing is chirping away. Nowadays, this pullet

sits on the sofa watching cbbc, spends the days plodding around in the kitchen and bosses 5 gun dogs around. Ace.
