We have about 6 older ladies and we've got 8 new chicks who are about 5-7 weeks old now probably (really not sure their exact ages but all but one pretty much are full feathered) 6 suspected pullets, 2 suspected roos. Question being, we've recently discovered lice on our 6 ladies and are treating them for a cold as well... I'm hesitant to start the integration because of the treatments we are doing, and because I don't want either to spread to the young ones. Is there a window I'm missing then here? Or if their kept penned near the free-ranging girls they shouldn't pick either up? I understand that the earlier you can integrate the better it is on everyone, but at the same time I really don't want to put added risk to the young ones if it's really not necessary. It would be almost another 3-4 weeks before we would integrate then which would make the chicks about 8-10 weeks perhaps. I can find info on fast-tacking integration but nothing about if you take longer? Hoping for some advice from someone with more experience in this department as these are our first chicks and integration. The new chicks when we do bring them to integrate will go into their own little tractor before going into the coop itself (we are in the process of building a new one so we would rather them all move in at the same time...?) Is this an OK plan? There's a part of me that is stressing out as I feel were missing an important window to get the chicks and chickens to know each other...but on the other hand safety first? Thanks in advance!
