Sorry, but this is going to take a minute to tell all the facts...I talked to a guy with several hundred 1 yr old Isa Browns he had bought from an Amish farm. He was selling them (he has other hens & he seems to know what he is talking about) and i bought 11 of the last 15 he had. When we talked on the phone he said these are "rough" looking but they will be fine - basically the Amish farmers rounded them all up a couple days before he was coming to pick them up and about 15 of them had feathers that looked rough due to the farmers putting them in too small of an area for a couple days. The guy i bought them off of said they were laying and were doing fine other than looking rough. I bought 11 of them - gave 5 to my brother in law who had a flock of 2 dozen or so that he wanted to add to and i kept 6. They were put into a brand new coop - built up off the barn floor with 6" of compacted dirt and 6" of pine shavings. The 6 had a fenced run approximately 50' by 20'. We put the 6 in the coop on a tues evening and they all were checking out the space just fine. The next morning, two were not moving much - we picked them up and took them outside and by noon they were dead. Wed evening the 4 were put into coop and all ran in by themselves. By thurs afternoon another one was dead. Same thing on the following Mon, one dead in the morning and another one dead in the afternoon after the weekend had all 3 doing very well and acting normally. As of today, we still have 1 that is doing fine, my brother in laws 5 are fine and the guy i bought them off of says the other 4 he still has are doing fine...what is going on?
