We got 11 1 yr old ISA Browns approximately 4 weeks ago. 5 were at my brother in laws and i took 6. 5 of my 6 died within the first week. One lived and did fine. the 5 at my bil did fine, last thursday we got the 5 from him and now have 6 fine hens but have yet to see any eggs. They eat Layena, have a 50 x 15 run they access daily, and get treates daily (some table scraps and cracked corn). They were laying when we got them...so i was told. Any thoughts other than be patient?
