So cold out this morning.. brrr. I have a question maybe someone will have some insight on. I have three young hens that just started laying in the last three weeks. I get between 1-3 eggs every day. They are on layer feed, I put oyster shell out for them, and they free range for about one hour per day. In the morning before I go to school, I give them a bit of leftovers as a treat (usually veggies, potatoes and grapes). Yestaerday afternoon as I cleaned the poop board, I found three eggs with a leathery shell under the bars. I had only cleaned the poop board two days prior. I am wondering what is going on, because it seems each girl is laying a good egg at least every other day. Any ideas?
