Last night, our rooster (6 months old) decided that he was NOT going to join The Ladies in the coop-yard at dusk! He remained in the garden and continued to cluck-cluck-cluck loudly, calling to our 15 hens to ‘return’ to him. Remaining unfazed by offers of scratch & avoiding being corralled, he continued to roam freely as the yard darkened. We continued to keep an eye on him as local wild-life would love a nice, warm Chicken Dinner! After locking-down The Girls, we continued our vigil; finally, Mr. Rooster decided to roost on an iron fence (only about 3 feet off the ground). Once it was dark, I plucked him off the fence and placed him on the roost with the hens in the inner-coop. If this behavior continues, he will not be long for this world (he seemed extremely determined)! I also do NOT want him to tempt the hens into joining him in the larger yard! ~~YIKES~~ My question is this: Do roosters (or hens, for that matter) just arbitrarily change their roosting habits and decide they will NOT go into their coop area at dusk in favor of roosting in the yard? Should I keep ALL locked-down for a few days? Any thoughts about this behavior, in general, would be appreciated; nothing in my Chicken Guide addresses this issue.
