We are new to chicken farming and are really enjoying the girls! We started this spring with 12 chickens, but are down to 10. In the last week, we've lost two. A roo and a hen. We think they both overheated after being "chased" by our kids. They weren't trying to be hurtful, they were trying to catch them to "play with" them. We have instructed them to leave the chickens alone and of course, they feel terrible. What would cause a chicken to overheat like that? They were two healthy birds. The rooster, it was a hot, middle of the day "chase". I can kinda see that. But, the hen, it was a cool, rainy evening. I don't want to lose any more peeps. Suggestions?
