Question for you experienced Java keepers - Are Javas usually quick to start getting wing feathers? Is it normal to have significant differences in the amount of wing feathers/growth in chicks of the same breed and age? (these are mottled javas)
Here's the deal - got 12 hatchlings (1 day old) last week. At 2 days old, we noticed that several had some pretty big wing feathers. I've got one now that has a full set of white wings and is bigger than everyone else. In fact, this one big thing is nearly as big as one of the 3 week old chicks that I also have.
Over the last week, we have lost 3 chicks to unknown causes. One minute they were perfectly fine, running around and then during a check on them (checking every 1-2 hours since I work from home), suddenly they were lethargic, couldn't stand. Warmth, electrolytes did nothing to help.
The first to die I think got trampled by the bigger ones - he was sitting by the feeder and there were multiple siblings walking all over it. The second had a scab on its butt - thinking it got pecked at by the others. The one that died yesterday died within an hour of me finding it weak and just laying there. Tonight, I've found one that is weak but can still stand - found it had a pasty butt so I cleaned off the vent. He is still alive but not wanting to drink and after I cleaned his butt and put him back in the brooder, one of the larger siblings came over and tried pecking his vent until I shooed it away. The rest of these guys are doing fine and running around like little lunatics. The one with the feathered wings - he (it) actually "flew" up to sit on top of the feeder jar the other day.
Hubby is a vet and we can't figure out what we are doing wrong (if it's us). We know that birds just die - hubby says he tries to touch his bird patients at work a minimal amount because birds are so prone to just croaking from being stressed by the littlest things.
Thing is, all the ones that have died have been "runty" compared to these others. The others are not only bigger, but they have if not full wing feathers, they are pretty darn close. These runts that have died - and the one that is weak tonight, did not have good feathers. One of them had no feathers at all - just fluff. The others just had the tiniest bit of teeny feathers at the ends of their wings - didn't even look like wings yet.
We also have a trio of 2 week old ones (they are now 3 weeks old) and one of them is nearly fully feathered, another is slightly smaller but has good wing feathers, and then the third is quite a bit smaller and has just the tiniest of wing feathers on the tips - it looks like the ones that have died, mostly fluff, just a little bit bigger. I've even been thinking I need to put it and one of the younger ones that is so much bigger than the rest of its group together - just to try to keep some of the smaller 1 weekers safe cuz it tramples all over them to get to food and water (even though it could just go to the other side of the feeder).
I'm getting frustrated since it isn't like I can just go out to the feed store and replace the chicks that have died. And I know that in breeding, you want the hardiest chickens cuz you don't want to pass on any genetic weaknesses. Since I don't know how fast these little Javas develop, I am trying to figure out if these guys that have so many wing feathers and are so big are going to be more likely to live and these others are dying because they are the runts and that is how nature works. Does that make sense?
So...is it normal to have a large variation in how fast they develop when they are the same age? Do they normally get feathered looking wings so young? Any ideas? It's really irritating me that I can keep all manner of mammals alive, but these little chicks have died on me - and it's really sad to see my husband the veterinarian looking at them and not be able to do anything either!
Answers? Thoughts? Am I nuts? Is there a "normal" with Java chicks?
