Try waiting 10mins or so after the first group have eaten before letting the second group out otherwise they’ll not want to fly for too long as they’ll have just seen the others being fed.
So funny to see you give in at the end and give them more food 😂 "ok, ok, you twisted my arm..." Also so sweet to see the white ones so excited to see you!
The problem is not with Titan, but his hen. If a hen is not a good feeder the smaller always struggle. You should pair Titan with the Adam's Hereman hen.
