I appreciate your response -- I was told to deworm the chickens after the 1st rooster died since I have no clue what he died from! He is going to the vet tomorrow to have wings clipped & spurs trimmed down so maybe he'll be good and leave a 'present' in the box for me as well - that way they can check him. I can't feed him separately since they all eat from the same feeder and the dewormer gets added to their food.
I was told to deworm them every fall to fend off anything they ate while roaming the yard -- is this true they need to be dewomer yearly? I'm also giving them electrolytes in their water - was told it just helps keep them healthy and they seem to add the little bit of powdered stuff that goes in their water -- just can't hurt them I would think.
Everyone has their own approach.
I'm personally pretty hands off. Don't care to have birds that need special treatment to be healthy. Survival of the fittest sort of thing.
My birds have been tough cookies. I've had two survive a hawk attack. It took them a bit too heal, but you wouldn't be able to pick them out now unless I pointed it out (one is missing a small chunk of her comb). Chicks go outside at 3 weeks, with a heat plate. I worm if I suspect issues. If a bird acts off I remove them, keep them in a kennel until a. they're better or b. they get worse and I dispatch them. I don't do antibiotics internally. Vet RX, Neosporin, peroxide/iodine and blu kote are my weapons of choice. If it needs more than that, I rather choose the soup pot.

There's no right or wrong way, just whatever you feel is right.
