I've lost 3 just today and a total of 6 altogether. I called Welp's and they asked if I was pulling their food for 12 hours, which I am. They said it may be too hot for them, so I actually brought them into the house and put them in the air conditioning, so they looked at me and then huddled together after a few minutes like they were cold. I have them back in their coop now and they seem happy. Anyone have any suggestions???:|
