I have a buff orpington who is about 4 and a half months old. She just started laying about 5-6 weeks ago. She is my only inconsistent layer (as far as I can tell), and has laid eggs with soft shells a couple of times when she was just getting started. I have 4 hens total, and at least one is still sometimes laying double-yolked eggs. It might be her. Now, she is spending a lot of time in the nest box. Last night I think she slept in there. I thought she was having trouble laying, and I felt underneath her but there were no eggs. She was making a purring/growling noise while I checked. She did this a few days ago, but later she was out and about and had left me an egg. Today in the middle of the day she was up there again, and again with the purring and growling. Is she having trouble laying? She is so young- is she possibly already going broody? If so, how do I prevent this? She has only laid me a handful of eggs so far! This is my first time with chickens, so anyone with laying hens- please let me know if you have any ideas. Thank you so much!
