I have 4 australorps that my BFF got for me from the feed store. A different feed store is getting chicks either today or Friday that should include silkies. I am planning to get one of the silkies at least, if not two. I also just placed an order from MPC for the rainbow layer special (vaccinated) that should ship in a couple weeks. My question is, do you have to quarantine chicks too? I know for grown chickens it's recommended but wasn't sure if it's necessary for chicks. Should I plan to keep my babies separate? And if so, how separate do they need to be? My brooder is a 55 gal fish tank so there would be enough room for all the babies when the arrive, it would be simple to make a divider. Is that enough separation or do they need to be in different brooders for a while then put them together? Lastly, if I need to quarantine them, how long should I do it for?
