hello today ive bought 7 white homer pigeons and 5 grey racing pigeons. The racing pigeons have 3 babies that came along with them but i am not sure which babies belong to which pigeons. i know that there is 4 paired pigeons and one male who is not paired and i am not sure who should feed the babies they are about 3-4 weeks old but one baby is significantly smaller than the others. are the babies able to keep warm by themselves now or do parents have to sit on them still? and also when will i be able to allow to let the pigeons out of the loft to fly them the guy i bought it from said i should keep them in 2 - 3 weeks before i let them out.
