I have bred lots of fawn javas this season, and i am in the process of deciding which birds to sell and which ones to keep for breeding next season. I know for a lot of species, the red eye mutations shouldn't be paired together as this results in weak offspring. Does anyone know if this applies to javas?

Matt, I'll take a stab at this one. The fawn mutation is recessive, meaning that the offspring should/could be smaller, there's no reason why this shoudn't apply to javas.

I would suggest split breeding the fawns to normals, which will produce 100% splits for fawns and then pair their offspring (the splits) to fawns again.

Hope this helps

Yeah, that was kinda my plan. I already have a few splits, but not enough to make up the pairs that I want, but I have plenty of excess fawns. I think I will breed them back to normals to give me some more splits.

Hi Matt

Hi Matt

Not sure where you live but here in the UK it is not unusual to pair visual Fawn to visual Fawn.

Yes we use the Normal to Fawn pairing to increase size but not all the tme.

I my time with keeping and breeding Fawns I only paired back to Normals if I felt the size of the resulting young was reducing in size.

But if you start off with good size and colour Fawns in my opinion you should not need to use Normals to bolster size and also depth of colour for 2 maybe 3 breeding seasons.

Just my thoughts Matt hope this is of come use.

Thanks Steve. Before your reply, I had a sticky beak at your web site and noticed some fawn to fawn pairings so my strategy now is to pair the bigger stronger fawns together, and the slightly smaller ones back to splits.

Thanks for the info.

Matt.
