80 degrees celsius (= 176 degrees Fahrenheit )
extremely hot... if you are only allowing it to cool slightly you can seriously burn the esophagus and crop to the point this chick won't survive it. You should know exactly what temperature the formula is in the cup before you feed. The temperature should be between 40 -42 degrees Celsius ( 104-107.6 degrees Fahrenheit)
Do you think you've fed the formula over 43 degrees Celsius ( 110 degrees Fahrenheit) ? The redness could certainly be caused by feeding the formula too hot.
As long as you are mixing the formula according to the package ( I don't know what formula you are feeding) it should be fine ( and the consistency should be like applesauce). If you have a scale that weighs in GRAMS you should be weighing this baby first thing in the morning before you feed him after he poops first to get an accurate weight. If he weighs 40 grams ( for example) you would feed 10% of his weight which would be 4 CC of formula. Be careful to NOT overfill the crop. So you can see how important it is to weigh and while you're at it record the date, time and how much formula you give at each feeding. It's also very important to keep the chick warm. A chilled chick can lead to the crop slowing down in digesting the formula. Below is a table of temperatures according to age of chicks as a guideline.
| Age | Temperature °C | Temperature °F |
| Hatch to Day 2-3 | 35.0-36.5 | 96-98 |
| Day 3 to Day 14-21 | 31.1-34.0 | 88-94 |
| 3 weeks to Weaning | 25.0-30.0 | 76-86 |
