I just happen to see this and let me tell you YAY!!.... well if you are wanting baby tiels anyway......

I´m on the same boat right now..... my Jack and Maui laid 7 eggs but just 3 survived..(4 were pecked I guess as they had lil punctures)...still I´m not sure if they are fertile... they mated and all but will have to wait till feb 10 or so to be sure

what was said is true hens might not sit on them until 2nd or 3rd egg are laid...so no worries there.... I´ve heard from a tiel breeder she kept one egg for almost 15 days and then adopted it out to another pair and it hatched....

and lone hens might lay eggs too if they feel the environment (food/temps/etc) is adecuate even if theres no male there

perhaps they were just "romancing" for the fun of it ...... now they just got serious

one more thing.... do you have pics of the happy couple??... I love to guess what the offspring might be like :P
