We have raised several batchs of young staying in the same flight, nps
And also had issues, more often than not, had issues with agressive female when she is out of the nesting box...
This can not only damage the other birds but effect the time she is off the eggs or tending the very young new chicks. _________________ My Spelling is Not Incorrect...It's 'Creative'
usually the hen doesnt worry till the 2nd batch hatches...If she is going to worry at all...
Over crowding maybe an issue... polution levels, depending on water supllies size of flight etc.
We remove the young just as they start to get the hang of flight, couple days out of the nesting box. to be weaned in another flight with single males who wean them off....
Definately before the beak gets full colour and iris forms. _________________ My Spelling is Not Incorrect...It's 'Creative'
We are keeping yellow headed rather than red, so maybe less aggressive...
We have three generations, about 20 birds, in the same flight with no major problems, two breeding pairs. Usually two or more birds will share the same 'roosting tube' ie drainpipe at night.
When both hens where sitting/feeding chicks was the time when there was some squabbling, but since taking nest boxes away! theyve all settled down again quite peacefully. Fledged chicks have never come in for much aggression from adults.
My suspicion is birds kept and bred in captivity for many generations lose some wild instincts through 'human induced' evolution.
Yes I have noticed that our yellow crowns are far more tollerant/ passive, espec the females at breeding time.

I sort of aggree and dont..
We notice birds several parrot and quail species that have been hand raised after serveral generations, loose the abilty to look after chicks, feed, and raise... in exteme cases will not even sit on eggs.
On the other hand things like uncling out fledged birds for single males to wean off....many generations and they still do so...as with most other behavours...
Natural Captive Flock social structures in larger holding flights get established very well, thats not lost, or maybe having the flock, bits and peices remain in each bird resulting in and overall recovery of instinctive social behavour......
Personally, observations even with a pair that has been isolated for many yrs, breeding, and generations of captivity, even these form smoothly into flock social structures...so dont think they loose that. _________________ My Spelling is Not Incorrect...It's 'Creative'
