I am going to foster 3 chicks and 1 guinea that are 6-7 weeks old. The lady 1/2 mile down the street was hit by last weeks tornado (strange for western massachusetts) and asked if they could stay here for a while until she can get the yard cleared and the coop delivered. My question is......do I house the guinea with her chicks, or with my own 7 week old guineas? My gut says to leave her with the chicks as she will be returning with them, and don't want her to form a bond with my flock and try to return when she leaves.
