Ah i see maybe these guys just take their sweet time absorbing the rest.
No problem, the chick has a really good feeding response so thats good.
I have used so many different types of formulas, from kaytee, nekton, zupreem, ect. Although for lovebirds i’ve used nutribird a21 as most lovebird breeders seem to use it. Right now I am also using electrolytes to replace the water, and bird probiotics (probizyme) to help out with good bacteria. Oh and I syringe feed, i find spoon feeding more messy and I cant see how much they have eaten.
