my hens Are just starting to lay, about 15 weeks old. 12 chickens and i get about 3 eggs a day BUT very cold here -20 C at nights still, but goes up to -5 C in the day can i let them out into their run yet, so i can clean the coop. I usually like to keep them in the coop for a couple of weeks before i let them out just so they know where their safe zone is and will go back in at night. Last year i had to pick them up and throw them in the coop at night, i am not going to do that this time as i have doubled my flock and these birds are too big.
Also..can i give them lettuce and scraps yet as a treat
Also should i give them oyster shells now
