I raise chickens, using an incubator and also broodies. It's quite easy as long as you learn all you can before you start.
Very important - you need to make sure you have the relevant manufacturers instruction manual for the incubator (what make and model is it?). Follow all the instructions for that particular model, as different incubators may have slightly different requirements.
Have a look at
www.pekinbantams.com - everything you need to know is on there. Very helpful and knowledgeable people on the forums.
Also you might like to look on the Poultry Club of Great Britain website.
If you manage to hatch any chicks - you'll need somewhere to keep them safe with a heat lamp suspended over them - study up on the website about heat lamp temperatures, etc. and relevant info for rearing chicks (all on the aforementioned website).
Chicks will stay under the lamp for about 5 - 6 weeks whilst they gradually feather up.
You'll need bedding for them (easibed) and chick crumbs containing an anticoccidiostat. Also a little water drinker suitable for chicks.
Also - have a think about what you are going to do with the cockerels that hatch - it's usually roughly a 50/50 ratio.
It's great fun watching them hatch and then rearing them on - but do a little research and I'm sure you'll enjoy the experience. It's not difficult - just research thoroughly before you start.
