I had 12 assorted fancy guinea eggs under a silkie hen in a very secure enclosed room in my barn. Eight had hatched out on schedule as of last night. They all looked healthy but I did notice that a few were already wandering out from under mama last evening which I thought was strange and a little early. I checked on them before I went to bed and all were under the hen and everything was normal. This morning when I checked on them just after day light, 7 had crawled out across the small space I had partitioned off for them and were dead or in the process of dying. They were literally a foot to a foot and a half away from her. I was sick to my stomach! Why did they do this? I have raised a lot of baby birds of all kinds like this and never had this happen. Any ideas?
