So I'm picking up 7 new chicks tomorrow. They'll be less than a day old, I'm getting them the day they hatch. Do they need to be quarantined first, or can they be put with the 2 or 3 week old chicks I've had for over a week now? The chicks I have now all seem to be very healthy.
There are two things to consider. First, are they coming from the same source or from a different breeder? If they are coming from another breeder, especially an unknown person or if you have not seen their facilities & birds, you should quarantine the new chicks. This will avoid introducing any possible illness to the others.
The second thing, like others have mentioned, day olds are so tiny and less agile. It's a good idea to keep them separate long enough to mature a bit. This will avoid any accidental injuries from the older chicks and let the new chicks get a better start, not having to compete for food or water.
Thank you. I think I will keep them separate for at least a week then.
They're coming from Papa Brooder on BYC, so I trust the source.
