I hatch and brood mine in the house. I have the incubator sitting on top of my brooder, so that I don't have to move them far at all.It makes me want to buy an incubator! Two things: 1) interesting that they moved the incubator (essentially) to the brooder environment at the start of lock down, rather than moving them to the brooder (barn) after hatch. 2) the hatchery birds in the study only traveled from 5-25 hours---the typical here is 40 hours, and up to 48 (longer, but you get dead chicks). So the weight loss and stress would be much worse after the typical 40 hours rather than 5-25 hours as studied. I don't know, but I'd expect the death rate, disease, etc to go up exponentially as time progressed.
