My kids found somepipping pigeon eggs in a nest up in the barn loft. We watched for an hour and the mom did not come back to the nest. I finally went up and grabbed them as my kids begged for me to save them. (They understand pipping, zipping and all that) One is pipped and appears to have quit. The other is almost zipped and moving in the shell. So against my better judgement, I grabbed them and popped them in an incubator we have running. It is too cold here for them to make it without mom. Any advice? No flames please. I don't generally interfere with nature but as a mama myself, I couldn't not give them a chance.
