The advice I read is to quarantine any new chickens for 30 days away from your existing flock. But our "flock" is 4 chicks that are 2 to 3 weeks old. Should we follow that procedure if we get a new chick? We lost a chick to wry neck last night (we think thats what it was. she suddenly could not hold up her head or eat or drink) We anted to get another chick to replace her now, while they are all still young and will be more likely to accept her. Is this a mistake? If we do get a new one, is it best to go back to where we got the other chicks from (if possible)? It was a feed store. Maybe they will be more likely to have the same germs that way? Thanks for any advice.
