So very sorry to hear. You have had a rotten time lately with chicks and eggs, I think.I don't have a garden this year but given the last few years I would say it's too early to tell.
Feeling slightly sick tonight. My 2 year old slipped into the incubator/egg room last week and cranked the Sportsman all the way up. I have no idea how long but it was at 105 when I realized it last Thursday (a week ago). I candled tonight and pulled out probably 85% of my eggs. I probably tossed 150 eggs. Interesting though that a few breeds had very low losses compared to the others: Ameraucanas, EEs, sexlinks (BCM X CL), and Exchequer Leghorn. I guess they are just very hardy breeds! We'll see how many hatch.
