Your backyard chicken who is allowed to free range will eat bugs, insects, and leafy greens. This is why pastured or free range chickens have darker yolks. The diversity of food sources going into the chicken affects the egg construction.
30C-34C is about 86F-93F! That temp will generally feel too warm for most people in a pool. A better temp that would suit more people would be around 27C-29C or 80F-84F. The water will still feel warm but still be refreshing when you're swimming. ... I think for 30-34 degree centigrade ambient temperature, the pool temperature should be around 81 F (approx. 27 degree C). This will make body feel fresh. For a ambient temperature of around 25 degree C and below, the pool temperature should be slightly higher at 30 - 32 deg C.
So here are the parameters for shocking your pool. If your water temperatures are below 50 Fahrenheit you should shock the pool once every 4 weeks. If your water temperatures are 50-69 you should shock the pool every 2 weeks. If your water temperatures are 70 you should shock your pool every week. Shock your pool if you have had a heavy rainstorm where you have to drain water out of the pool. A storm like this will drop algae, food for algae and other contaminates into the pool water.
