chicken newbies with a few questions..

Buff Orphington's are great mommy's and this may stimulate the hen that is not laying well to go into her cycle. A buff will usually give a abundant 220 eggs as a average in one cycle. I give a five way scratch grain and plenty of gritt and oyster shell for calcium this will give the egg it's ability to form in the hen with out taking extra nourshment from the hens strength. I would not hesitate to put the new baby's in the house only after they are about 5 to 7 weeks old, this is when the fluff has matured into full feathering one of the reasons for not putting the young chicks with the older hens is because they will try to get under the hen, this will upset her because she is smart enough to know they were the eggs she sat on for 28 days. Also make sure the new chicks are active enough to run and hope to get there own food with out needing to be shown what to do. the effort is rewarding.. Good luck

 

If she's only 2 years old, age isn't the problem. She's probably stopped laying because of the stress of going to a new home, unless she went broody. Is she acting normally or staying in the nest all the time? If she's acting normally, she probably just needs a little more time to go back to laying. She had to get used to new caretakers, a new coop, a new run, new water, possibly new food, a new schedule and a new environment that may have different animals in it, wild or domestic. That's a lot of changes all at once and chickens are not big fans of change.
