I have 4 EEs that are somewhere between 7 and 8 weeks old. The girls are fully feathered and have been ready to go outside for some time. But the little rooling still isn't feathered out. Sort of waiting on him to finish getting in his back and bottom feathers :/ I need the larger indoor brooder for my younger chicks so I was hoping that maybe he could go outside in the tractor? He'd have the 3 pullets to snuggle with at night. Temps at night seem to be 40s - 50s. Daytime should be pretty warm this week. There is no heat source in tractor. Thoughts?
