You wondered why I had not been posting photos over few past months. Reason: my budgies are in moult.
1st photo: 3-month-old female SF YF1 SF violet-skyblue normal budgie, in first stage of moult, started to moult on last month. Primaries 6th missing.
2nd photo: 5-month-old male SF YF1 DF violet-cobalt normal budgie in moult.
3rd photo: 7-month-old male SF YF1 SF violet-cobalt normal budgie in last stage of moult, will finish moulting on early May when all last growing feathers are fully grown. Primaries 10th are not fully grown until later this month.
