Hi guys!
In my first post here in this forum, I'll get started right away:
After fifteen years of keeping budgies, I started the budgie breeding project this March. I started breeding two pairs, one of which had to be cancelled. One pair (Female about one year old, male about three-four years old) continued to breed and on Monday a week ago the first chick hatched. The second chick hatched exactly two days later. In total, there are two hatched chicks from two eggs (there are always at least 3/4 - 6 eggs, but I explained the two chicks to myself by the fact that there are probably so few simply because the pair hatched for the first time).
The pair currently breeding is in a closed Montana Paradiso 150 cage, no other bird have access to it.
In preparation, I gave them lime additive and germination feed. So far, they have also been given sepia, gritstone and molt salt during breeding (and before!). Now, after about a day, the second chick has developed bleeding on the head. They have not been given an fruits or vegetables (i'm trying since a few years to get used to all sorts of veggies, but to this day they seem to dislike them (not giving up though

)). The growth seems normal to me (on today's fifth day it is already opening its eyes a little).
Now my question:
Have you already observed something similar? I expect every day that chick no. 2 will not live any longer as I cannot imagine that such a head injury is survivable. The pattern extends sideways to just before the eyes and in a line across the head to just before the nose. It is somewhat raised.
I have already consulted a specialised avian veterinarian about this (Dr. Christen, Winterthur). She advised me not to do much and to observe it. Since the little one had already grown a bit and was already opening its eyes, it was possible that it would get by.
I am more than happy to answer your questions and of course always open to suggestions for improvement.
With best regards from Switzerland,
Irene
