So I think I'm going to add a couple roller pigeons to my bantam coop. The bantams in it (d'Uccles, d'Anvers, Dutch, Pyncheon, EEs) are only 9 weeks old they are currently significantly smaller than pigeons, so it seems like it would be good to add the pigeons soon. Im planing on adding some seperate higher pigeon perches, but I have a couple questions about what else I would need to do. Can pigeons use a nipple style waterer? Its just a 5g bucket with nipples in the bottom, hung up 6in off the ground. Can they be trained to use this? I wouldnt mind in the summer offering other water, but I have to use a heater 5 months of the year, and I don't really want to get another heater waterer. Also, will pigeons return to roost in the coop at night on thier own? The run is covered with netting, so they'd be able to fly around in there without escaping. Anything I'm missing, that I need to know? Any other tips?
