I bought a RCOM PRO so very this is automatic. The only thing that is concerning me is the candling. I put the incubator in the cellar as advised in the “incubating at home book by Michael Roberts, but it is quite cold down there and when I open the lid of the incubator the temperature falls like a stone.
It would be a great help if anyone could help me on the following question.
Do I have to lift the eggs out to candle or can I leave them in the incubator and just put the light on them.
Would it be a good idea to place a heat light over the incubator for the candling period as I am not going to be as quick as a professional.
It's best to keep the incubator in a room which is as stable a temperature as possible and is warmish. Ideally you are trying to maintain stable conditions so temperature and humidity doesn't vary widely requiring the incubator to compensate for rapid changes.
Incubate broad end upwards. I think it's best to not disturb the eggs too much and I just open it to top up the water for the humidity. I candle twice or three times at the most. After 6 days (the most important time to check all eggs to remove infertile ones), 12days (to check development, not necessary to check all just sample candle), 18 days (not vital as at this stage you probably are going to let them run to full term anyway and it's just for interest really.) At 18 days raise the humidity by following the manufacturers recommendations.
When I candle I lift out all the eggs on a tray and cover them with a warm fluffy towel to minimise the heat lost. I replace the incubator lid to maintain humidity and temperatue. I lift out and check the eggs individually and replace them immediately under the towel so thay don't drop much in temperature. No need to heat the eggs as they will survive short periods of temperature dips during candling, just insulate them with a cloth cover.
If you use a fine mister to raise the humidity after returning the tray to the incubator do so sparingly and don't wet the eggs. Humidity shouldn't be too high before 18days. Raise it in the last 2 and a half days when you should stop turning. Don't lift the lid during hatch until half have hatched and no more frequently than once per 6 hours. Remove chicks to a warm bucket for transfer to the brooder. Remove empty egg shells at this time also. Keep lid off at this time as short a time as possible as high humidity is most critical at this time .
Simple evaporation pads can be made by using kitchen paper folded into strips about 3inches wide and one end dipped into the water trough to wick up the water and evapourated from the rest of the pad in the incubator.
