We have 14 pullets that r about 6 weeks old and 5 guennea chicks about a week and a half old separated by a wood spacer right now but in the 15 x 15 coop. We have a 10 x 15 covered run in the back attached to the coop. We let the chickens out in the run during the day and back in at night. At what age can we let them out in the yard and what do u suggest doing with the guennea chicks? Put them out all together or keep them separated for a while? Virgin new at this!! Thanks!
