cooked grains with egg yolk and brushed broccoli is a huge success! Even the cock comes to eat it, and he is a famous stubborn "only one food eater". Especially they liked couscous, today I gave them cooked millet (never paid attention to it in the stores before), quinoa wasn't a big hit, along with oatmeal, but they liked cooked rice in the same combination. I cook one egg for them every day, and I only feed yolk, but still lots of it ends up in the trash. I hope its not too much egg for them, is it? remember I have 6 birds eating half the egg yolk twice a day.
What do you think about margarine? I always thought its s big junk, but I was told a lot how important it is to feed it to breeding parents...sometimes I am tempted to mix cooked grains with vegetable "butter" spread.
Yesterday younger birds went outside in the cage. Today same sunny beautiful weather, but I am not sure if I am going to take them out. A whole thing is such a big deal for them, long time to catch, and everybody behaves like something really bad is going on. Well, they are unfamiliar with this, so I understand. Parents stayed indoors to assist baby chicks but they got spooked by my actions too. Interesting but young birds have no problems to land on me, one at a time or all together. Sometimes I am all covered in birds!

I would suggest giving less egg. I cook an egg then cut it in pieces and store it in the freezer, so I can take out a little bit at a time and thaw it out for the birds. I have 13 cockatiels, and one egg provides quite a few servings! The usual recommendation is 1/4 to 1/2 teaspoon of egg per adult-sized bird, and I usually aim for the low side. The parents can have some every day since they have babies to feed, but the older chicks would be better off getting it twice a week.

I don't recommend margarine for birds or humans either, and I don't think it's necessary to feed oils. They do need a lot of calories when they have babies in the nest, but the original seed or nut that the oil came from has a lot more nutrients in it than the oil itself does, because most of the vitamins and minerals are left behind when the oil is pressed out. So for example they're better off eating sunflower seed than sunflower oil.

this is how eye looked before I cleaned it

After I cleaned it, his left eye is certainly better but still I can see that he favors it, not opening all the way. For comparison, this is the right, not affected, eye

this is the affected eye yesterday, 24 hours after I cleaned it. I can see that he doesn't open it as wide as the healthy eye. At some points, he completely closed his eye while the good eye was open normally. All this the day after I cleaned it. SOmething to worry about and take him to doctor? How his general development looks? He is exactly 2 weeks old on the picture. He always had the second smallest weight, as he is 4th chick that was born, but yesterday the youngest weighted as much as him. Also, he looks not as round as the youngest baby, they have 1 day difference in age.

Could it be poop in his eye? Does he need eye drops?
Nearby I have a general vet who sees birds. Not sure how experienced he is with birds. He treated minor problems for us in the past. He also treated my bunny when he had eye problem. Avian vet is 1 hour drive from me

parcel with formula arrived. the bag got cut somehow....just no luck recently.

His development looks good, and maybe that eye is just opening a little more slowly than the other. For now you can just wait and see what happens. If his weight gain continues to not keep up with the other chicks you can do some assist feeding.

I love his yellow crest! Im sorry for not giving any advise this whole breeding journey, its a little beyond my breeding experience. I definitely learned a lot! Thanks

thank you all.
Guess what I discovered in the nestbox when cleaned it yesterday? gray and black MOLD where the poop was! I cleaned it several days before yesterday. I normally empty the nestbox into a large trash bag, and keep this bag closed in the room for the next cleanings, until its pretty full, and then I throw it away. The bag was emptied once before yesterday and it also had mold inside! When I clean the box, I wipe the walls with damp cloth to remove poop from the walls. I dry it with paper towel before I put new bedding. It's not completely dry when I am done but I think its almost dry. Last clutch I did the same and had no problems. Does it mean that humidity was really high???
Hopefully none of the babies got sick. They look OK. Also, the eye of the chick #4 looked normal yesterday! The oldest chick weighted 98g yesterday, and two youngest were 75g each.
What in general is feeding pattern for the parents? Will they feed as much as they can until fledging and then babies loose weight due to activity, or will parents start feeding them less too?
