I have a 24 bird basket in my young bird loft,when the youngens are put through the flap is left open for them to sleep in or whatever,once they start perching the straw is removed and the flap closed.I then use the basket to get them use to going in and out of it and feeding in it,but just a small handfull of black rape.Open the flap throw in the rape and you have 90% of your youngens in the basket, also take the drinker out of the loft and put drinkers on the basket,it works for me.
