My 15 brahma hens were laying about a dozen or more eggs a day. When the weather got better I started letting them out in the pasture to forage during the day. After a couple days of foraging I noticed the daily eggs declined to only about 5 or 6 so I put the hens back into the coop day & night. Why are they still only laying 5 or 6 eggs a day? What can I do to increase their egg production to what it was before I started letting them outside? Thank you in advance for any help with this.
