I've been losing at least three Wellie chicks lately in the past week,probably due to rats. Im down to four cockerals and two pullets However no blood, bites, feathers, lice/mites or illness/sickness was found on them, they were healthy and eating and lively. Whats the cause of sudden death? Could the rats bitten them? They died almost in the same spot. We got major problems with city rats, no signs of them except for the holes under the coop. There is a small cage in the coop and dunno if they ran blindly in the darkness and broke their necks or perching on top of the cage, they fell off? Whats going on????????????
