If Chicks Get Wounds From Being Pecked Dab With Auto Grease

We do this too.  Works every time!  Only we don't use a grease gun.  We just scoop up a dab on a finger, then smear it around the feather-pecked area.  The chickens hate the smell and stop pecking right away.

We do the same thing. No more pecking after the grease in on....

Curious to know if it stops the squeaking too?

This made me laugh!! 

I have a baby chick (about 10 days old) that got in the middle of a fight between mother and the rooster just this afternoon.  Chick ended up down and the rooster pecking it's neck.  I quickly removed it from the run thinking it was dead.  Turns out it's a tough little bugger and is now loudly cheeping for it's mother.  If I grease the wound, will this prevent the mother from pecking it?  I thought that maybe I could separate her and the chick in a pen in the coop until it's MUCH bigger.

I think pine tar is a much safer and more effective treatment for wounds.
Pine tar has germicidal and healing properties.  To my knowledge auto grease has none.
I recently treated a large gaping wound on a turken with pine tar.  If this wound had been on a human it almost certainly have required stitches. 
Three days of treatment and the wound is healed and the skin looks great. 
Had pecking of the wound by her flockmates been a problem, the pine tar would have solved that too.
Just MHO.

My 8 week old got beat up by the older girls. I ran up to the garden and I thought she was dead when I saw her. But I called her name and she jumped up and ran to me. She lost a lot of blood and has a big open gash under her wing but she's doing very well this morning. It must look worse than it is. She's covered with antibiotic ointment at the moment.
How long after you put the grease on does it keep the pecking from happening? Do you have to reapply often?

Auto grease is full of heavy metals; moly and several others.  If it's not fit to use on a human, it's not fit to use on a living animal.  Use petroleum jelly, available at any drug store or Walmart.  While I wouldn't eat it, it is safe to use topically on animals.

Not that I agree or Disagree, but just to balance the argument, most human medicines are full of toxins and poisons too.
