I recently bought 4 19-week old RIR/WLH to start laying eggs while I wait for my 7-week old Easter Eggers to begin laying. The laying hens were definitely intimidating the little ones, chasing them around the run every once in a while and sometimes pecking at them but since they never broke the skin and the littler ones were good at getting away, I left them together. We came home a few nights ago and one of the Aracaunas was dead in the middle of the run. No sign of blood or fighting. I am new to raising chickens - should these ages not be put together? Should I separate the three remaining pullets from the laying hens? Since this has happened, we've not gotten any eggs at all. I don't want to lose any more of them! Any suggestions? Thanks!
