So currently our Cochin has gone brood and our hampshire I'll refer to her as Dori is exceptionally needy and bossy about this 'abandonment' I've heard that brooding can trigger in other hens to also brood which I've seen whith a dominant roo s flock in breeding season. But now She's been somewhat inspecting different spread out nesting spots from normal such as the nest box in our YB coop going in and out and in and out and also will arrange any eggs in nestboxes specifically even when not pre /post immediate lay. I've never noticed this whith other hens who've brooded but is she looking for a suitable nest sight? And if so how good of mothers/borders are they? I don't think I've ever seen a NHR whith chicks but if she may become an intent brood I may give her some eggs to hatch.
