Broody or sick?

Hi i am quite new to keeping chickens and i only have 2, My light sussex i thought was going broody but she used to come out for food etc, but for the last few days she dont want to come out at all! She isnt making any noises and doesnt try to peck when moved. She is still laying although thismorning found egg on floor not nest box so she must have laied while purched! I have locked her out for most of today and have seen her eat a bit but shes just stood on the ladder by the door, Her eyes still look bright abd comb is still red, should i be worried??

Hello Hurrooke and welcome to the wacky world of henaholics  

I would agree with what PaulineM says and, like her, I'm not that experienced.  As well as checking the temperature you could check some other "usual suspects"

crop - is it hard or soft and squidgy
little visitors - has she been wormed recently, could there be lice or redmite
Poos - there is a good guide to chicken poos if you type that into the search box you will find some good info.  Can't give you the link just at the moment
eating and drinking - is she doing this as normal or has the pattern changed?
movement - is she moving around OK or is there a limp or slower stiffer movement or listlessness
age - how old is she?
breathing - is her breathing noisy or silent?  Is she coughing or sneezing?  Does she have a runny nose or runny eyes?  Is she gaping or shaking her head?

Although you probably won't need it, it may be a good idea to identify a local chicken-friendly vet for if/when you need one.  Not all vets are chicken-friendly and some will not even treat chickens at all.

I'm sure that more experienced people will be along to give you advice; in the meatime Good Luck and keep us posted.

I had a broody who I gave in to and gave some eggs, she wouldn't poop in the old nest box and now she has eggs she won't come out at all unless I lift her and she holds onto her poop until she comes out and does it all in one go!! She doesn't eat much either and is very hot underneath and you can feel her skin where she has plucked her chest feathers out.  Her comb is very pale too.
