I have a one year old Buff Orpington that has been in the laying box for about five days. She has laid in these past five days. when I pull her off and put her in the yard she'll scratch around but when the others come around she puffs up and gets defensive. She will not go to roost. She is eating and drinking and takes her dirt bath when I take her out and physically put her in the sand. This is not her personality. She's always been our social butterfly, but now she's a hermit. Is there anything I should be doing or just let her do her thing?
