I was getting about a dozen, maybe more, eggs each day from my 20 standard size mixed chickens. Then we had a miserable, humid heat wave, with 100 and over temps for a couple weeks. My hens dropped off to 5 or 6 eggs a day. anything I can feed them, or do, to get them back on track? I made sure they had fresh, cool water a couple times a day (they always had water, but I mean I changed it a couple times a day) and they always have egg pellets. Then I tossed in any watermelon, cantelope rinds and also any damaged tomatoes we had. Tossed in BOSS a time or 2 a week, and also toss in some scratch once or twice a week. any ideas? Thanks.
