The earlier the better. Adult chickens don't see little chicks as competition for status or food. Could be your lone bird will be really happy to see the chicks, she's gotta be lonely in a flock of one.I might leave the chicks in the sunroom for a couple of weeks first it's nice and warm in there.
How soon can I introduce the chicks to the one I have?
Just how warm does it get in the sunroom?? Too hot is a problem. No way you will have any temps too cold in the summer. In fact Blooie (who started the MHP thread on BYC) stuck hers out in subfreezing temps at a few days old. I prefer to get my chicks in mid spring because they SHOULD start laying in the late fall and lay through their first winter. Of course all but one of the girls I got last year didn't read the rules, 5 of them started to lay, then quit. The one that started the latest laid through the winter. All the girls in the prior 2 batches (early/mid June 2012 and 2015) laid through their first winter.
