No eggs in a few days

Hello, I have enjoyed my hens and coop from Dare 2 Dream since 2017. They are nice egg-layers as well. I am concerned about Goldie, the sex-link, who just sits on her hocks most of the day. She will take a few steps and then sit down and does not go up/down the ramp. She was getting picked on, so now she is separated and is brought in to the house at night. She is skinny despite eating. I am providing TLC and after a month, brought her to the vet. He really couldn't tell what was wrong with her w/o blood work and scans. Her poop tested normal and she does not have lice or mites. I added B complex to her diet a few days ago. Do you have any idea what this could be? Thank you for your knowledge.

Hello all! We are newer to the central coast; transplants from WI. The house we purchased came with a very sturdy coop and enclosed run about 10x12' in total size. My parents raised meat and laying chickens, so I understand the basics of their care. But, it was a different climate in the upper midwest. We are going to start with full-size chickens instead of chicks. Two questions - 1. How many chickens would be a good fit for a 10x12' coop? 2. What advice do you for a newby?

I just put a chick under my favorite hen two days ago (from hatchery,i dont have a rooster ) , i have them separated with wire from the other hens, she has been bringing her out to scratch ,etc. When is a good age to remove the wire and let them join the others ? She is very protective of her chick! Even puffs up and sounds like a raptor to me !
