Thank you so much everyone for trying to help. It's so very appreciated. They are both penned and free ranged. I had them in the pen this morning because I have mama hens and babies in the coop, so I've been keeping the roos out of the coop during the day. But, I really have to think it's the peas or the watermelon BECAUSE, they were all roosters that died except for one hen that I let come out because she hasn't been broody or sitting on chicks, as of recent. So she hasn't been free ranging much at all, maybe out for like 15 minutes yesterday?? She was in the run when I fed the roosters, and she's now dead. I have three hens left in the coop that are fine. They haven't been out at all.....
