help chickens are getting sick

[bravofarm]

I was looking at my chickens and noticed that they are starting to maven less and eat less than normal. I have no I idea what it might be or what to do. Also they have lost a lot of weight.

Feel them up for skin injuries and possible internal issues. Before you do that though, smell her. If she smells like rot, immeadiately look over all of her body for maggots. Try worming her or try to feel for an egg that might be a little plugged up. If you think it's an egg, wash your hands really well and use some olive oil to lube up her vent and massage her area down there to try to get it through. If it's maggots, spray some of them off with a hose, get some screw worm spray from TSC, spray it on, then wash out all the dead maggots, spray some Hydrogen Peroxide on the wound, clean it, cover it in Neosporin(no pain relief), seperate her from others and flies, and give her boiled egg yolks. If it's internal, try antibiotics, then try a vet if they can't do anything, I'd put them out of their misery. Sorry for this being so long but those two things can be loads of stuff.
