I just want to point out to some "newbies" here that I cannot stress enough how important it is to quarantine ANY new birds you acquire, whether members here or other sources. Family, etc...doesn't matter. ..if you care about your birds and do not want to be in a position to have to put them all down or be limited to not moving birds off of your property because of disease. ..Quarantine
Most good Biosecurity measures are for at least 30 days. Granted there's always that risk of it not raising it's wary head during that time but like @jenaman experience and @daskhan for reasons such as getting accustomed to a new place or being able to keep a better watchful eye over behavior and health to know it's not because of a new pecking order but it's a problem with the bird.
Food for thought!
You'd appreciate finding something out in quarantine rather than your entire flock that you've worked so hard to build.
I cringe every time I read that someone has put a new bird right in with the others. Petrifies me!!
**edited to add**
Quarantine can be as simple as having a decent sized carrier or crate or box that is not going to be used for any other purpose. Typically diseases are passed via saliva/bodily fluids which keeping them to their own feeder and waterer, only using a specific clean scooper for them in their own feed container, washing hands thoroughly and tending to it after your own birds and ideally located in an area (shed/garage/basement) that your other birds/chicks aren't in. Because some diseases are airborne and take no more than some dust particles to transfer! May seem extreme at times but I'm telling you there are countless tears shed over this very thing by many loving poultry owners!!
Huge hugs to everyone as I only post this because I care!
And I can 2nd that. I made that mistake when I first got into chickens and had to cull my entire flock. It was heart breaking and I never wish that on anyone. I have a Quarantine area and I keep it. Its a outdoor dog kennel that is in a yard that the others cant get near. I started out doing it for just 14 days, that's not enough. So now I do it for 30 days.
I am doing it form now on with my goats a full 30 days too. I just today lost another goat kid because I didn't Quarantine a new goat.
@jchny2000 I lost Bub today at 9 am. For those that don't know Bub is the goat kid that surprised us all in may with his arrival.
RIP baby boy, I will never forget you.
