Why won't my chickies lay eggs for me? They are between 18-20 weeks old and several have very red combs. I have supplies nesting boxes and hay, my two roos are interested in them. Giving them Treats of watermelon and veggies. Layer pellets. The only thing I can think of is this blasted heat topping out to at least 100 every day. They have plenty of fresh water and an "air conditioned" bucket (with a frozen milk carton inside). I have put a golf ball in one of the nests. Is there anything else I can do???
