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.
Most spas control systems have a maximum of 40 degrees Celsius, however 40 degrees is not a recommended temperature to spa in. Some Like it Hot, Hot, Hot! The reason spas have a maximum temperature of 40 degrees is for safety reasons. Any outdoor spa that goes over this temperature is not fit for use. A recommended temperature setting for an outdoor spa pool is around 36-37 degrees Celsius (blood temperature); this is more comfortable and allows for a slight temperature drop whilst in the spa.
