I have raised my flock from eggs and have never had any problems with my hens laying. About 3-4 weeks ago I bought 3 adult partridge brahma hens from a woman who I trust to have good birds. They are adult hens and look healthy. I have had them in quarantine (thank you BCYers for teaching me that). In the 3 weeks since getting these girls, I have very sporadically gotten eggs. They don't roost or go in the laying boxes. The eggs that I find are on the ground. I am getting a total of 1 egg every 2-3 days. In the weeks I have had these girls I have gotten approximately 6-7 eggs total! I feed flock raiser, a little scratch, BOSS, table scraps, fruits, veggies, etc. I have an open bowl of oyster shell and grit for them and they get plenty of fresh water. Any suggestions? Is there any way to tell if these girls are too old, or does it just take time to get them acclimated to their new surroundings?
