Yes, your 4 month old still has some filling out to do. Although he is for the most part 90% full grown he will fill out significantly over the next few months. I have found that They don't achieve full size til they hit adulthood at 8-12 months ( dependant on the bird )
My pied RF took about 11 months to get to the size he is.
Enjoy your Boy. Cheers!
Occassionally we do get a small male or female
When er have breed off these, it doesnt seem to make any difference to the off spring.
Sometimes the complete opposte, a ave male and very small danty female have produced some of the biggest females I have ever seen. larger than the ave male
The odd part is althu she is huge in the body, the beak is still the normal size, so at 1st glance she does look a bit odd
We have here currently paired up this season _________________ My Spelling is Not Incorrect...It's 'Creative'
I do belive hand raised are generally a little smaller than well supplied nest raised
All our birds are nest raised, then tamed after if required _________________ My Spelling is Not Incorrect...It's 'Creative'
An interesting subject in this matter is called 'Heterosis' or hybrid growth force. This occurs when both parrents are very distant related.
Below is an abstract of what I've found on this link: http://www.canaries.org.uk/download/inbreeding.html
It is worth to put it in a frame and hang on the entrance of every breeders aviary.
When you have a champion racer from an outcross mating, you have a genetically unique bird that has never existed before. There are gene combinations in that bird that do not exist in any other bird in the world. The trick is to pass some of those gene combinations on to as many offspring as possible. Breed the champion to as many different mates as possible, while keeping only the best youngsters. Next let these youngsters mate to distant related mates. Keep only the best youngsters. These second generation youngsters then should be mated to cousins that have the champion in their pedigree. Hopefully, some of the gene combinations that made the champion a champion will combine in these cousin to cousin matings. If this happens, then desirable characteristics have been fixed in the resulting birds and a family based on the champion genes can
be established through further gentle inbreeding.
The other side is that we breed away from the original form.
