I bought 25 golden buff chicks in Aug 27 and sold 10 of them in Jan. I talked to the lady I sold them to a few days ago and she said hers had been laying for 3 weeks. There is 19 pullets in a 6 ft by 20 ft pen a 6 by 6 house. There is not any roosters in the group. They are a little over 6 mos old and I can't figure out why they want lay. Included in the 19 are 4 Dominique and 3 rir the same age. I wormed them several days ago with goat wormer. I sure need some help here. Thanks.
