mist spraying broody hen's eggs

I've never used a broody before, but never heard of spraying the eggs.  Birds have been hatching eggs for thousands of years unaided.

As to the purple spray, I suppose you could try it, but as egg shells are porous, it may affect the developing chicks?

Welcome back bantam novice.  Never had that problem with my broodies but I would go with leaving well alone.  Could it be the bedding that has caused the bleeding?  Also check broody for mites/lice, if she has something irritating her that could be the cause.  A sprinkling of diatom in the nesting material may help.

If you are worried about the broody getting an infection try applying a tiny amount of cornflour to the sores.

Thanks guys!
I am so grateful for your responses.  I do feel that leaving mother to herself is the right option.  The eggs have started pipping now so I'll just sit on my hands and let nature take its course...however tempiting to peek!  That is really the hardest pert.

Two hatched and four pipping!  I will post pics when I can take a photo but don't want to disturb mother broody just yet.

Well we have four sabelpoot chicks and a nervous mum.  Two hatched out but mother was moving around a fair amount.  When I looked in there were two on the bedding and I thought they were dead.  When I picked them up they felt cold but were moving so I popped them in the inccy on a lower temperature but warm enough for brooding. 

I thought I had lost them both but the next day one was fluffed and standing though the other was on its side and seemed unable to get onto its' feet though it was moving quite strongly.  When I looked closely the head seemed tilted and one eye lower than the other.  It looked almost as if it had lost the use of one side.  I dipped their beaks in water laced with honey and put some chick crumbs in. 

By this morning both were on their feet.  Although Igor(ina) was still tilting a little to one side s/he was pecking at chick crumbs and drinking and both chicks seemed well enough to try and put back with mother and her two other chicks. 

I checked on them just before shutting them up for the night and mother seemed to be settled with all four chicks under her.

I don't want to unsettle mother until she feels ready to lead the chicks outside.  I will  take pics in a couple of days.

Hello there,
here is a picture of Igor/ina with his/her mum and siblings.  Igor/ina is the chick closest to the camera.
