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.
The science behind pool temperatures: To raise the temperature of one gallon of water by one degree Fahrenheit requires 2,100 calories or 8.33 BTUâs. To cool a gallon by one degree requires getting rid of the same amount. Therefore to raise the temperature of a 10,000-gallon pool by 1F would equal 21,000,000 calories or 83,000 BTUâs. The same goes to lower each 10,000-gallons by 1F. The sun can increase the temperature of a pool by 3-4 degrees Fahrenheit on a sunny day. As the pool temperature reaches equilibrium (similar to surf temperature), the daily influence would be less. Heat pumps and chillers are rated by BTU/ hours so you can actually size a unit to provide proper cooling.
