Getting ready to cull this pullet,comments welcome

[Samjoe]

As of 3 weeks ago my chicken experience has been perfect. I raised 6 production reds from day old and they should be laying any day now.I made a mistake 3 weeks ago and lost 2. I got too comfortable with free ranging my birds and they wandered out of sight near some woods and were attacked. I thought it must have been a dog but one was carried away and my reading tells me more likely a fox or a coyote. Bot are common here in rural central Kentucky. As we so often do I compounded my mistake with more problems.
In my rush to get back up to a full house I found an ad for pullets and drove out to buy them.They had a two Barred Rocks and a White Rock ,just what I was looking for. I should have NEVER bought these 3 chickens. I knew they were filthy and rough looking,but I drove almost an hour to get there,and my 2 boys were expecting to bring home chickens.I get them home and immediately know I made a mistake.Poor is not the word,but I kept them seperate for 5 days and put them on acv right away,clean coop and fresh water.The 2 Barred Rocks cleaned right up and and have found their place in the flock.The White Rock perked up good too but has regressed,he was the worst of the three with a rattle in his breathing and a generally poor condition. The rattle is back and now he has a scab or wart over one of his nostrils.I am ready to cull this chicken.Not because I can't deal with a sick chicken but for the sake of my flock. My reds are perfect with hardly a feather missing.Im worried I have already put them at risk and don't want them exposed any more than I have already.feel free to comment. BTW the Barred Rocks cleaned up good.

Unfortunately when you put the new ones into the flock without quarantining them for at least a month, you may have exposed them to carriers of a respiratory disease. Culling is the best thing to do, and watch for any similar symptoms. Mycoplasma (MG or CRD,) coryza, and ILT are some of the common diseases. If you could take a picture of the wart on the beak, it might be helpful since canker or fowl pox could cause that. Here is a link with the symptoms of some of the common diseases and one on canker:

I'm learning some lessons here,here are my mistakes as I see it.
#1...I got too comfortable free ranging my flock in an area full of wild critters
#2....I rushed to replace my lost hens
#3.....I purchased replacements from someone raising chickens in poor conditions
#4.....I didn't quarantine my new chickens long enough.I wasn't set up to keep chickens separate long term,an excuse I know.
#5....I added new chickens to a flock that was already reorganizing from losing 2 members.
#6....I added 10 week old pullets to a flock of basically full grown chickens,the person I bought them from said they were 16 weeks,they obviously weren't.
I really don't know anyone raising chickens so I've basically learning as I go,none of these things will happen again.

It's done and I'm an idiot.These birds are counting on me to keep them safe and I've failed them. Moving forward I'm going to redouble my efforts with what I have. Jeez
