Thanks so much for replying. We just finished the bag of chick feed, so the next one I get will be the raiser feed. I have a watermelon right now, for my kids mainly, but I could give some to them...should be loads of fun to watch. It normally doesn't get too hot here in the summer (maybe a week or two if we're lucky) but if it does, I will take your advice on the electrolytes for them...great idea. I just love our chickens so much and want to make sure I'm doing everything that I can for them so thank you again for your reply. Rachel
