About a week before Christmas, I replaced my 3 year old layer flock with young pullets. I bought three 8 month old Barred Rocks, an 8 month old Rhode Island Red, an 8 month old Banty Golden Laced Cochin, a 4 month old Aracauna, a 1 year old Blue Orphington, and two 1.5 year old Arcauana's. I realize the "older" ones won't be as prolific, but it was a package deal. The banty laid daily for the 1st week, and then hasn't laid since. The Rocks and the red were laying 1 or 2 a day for the 1st week and nothing since. One of the Arcauna's layed every other day for the 1st two weeks and nothing since. I supplement the lighting so they have 14+ hours a day. None of them are molting or showing any signs of molting. Plenty of fresh water, food and I give them scratch grains twice a day. The past couple of days, my Rocks are doing the egg squawk, but no eggs. I can't figure out what is going on! Any thoughts???
