I also don't have mutch knowledge but maby if they see you in the pond maby they will see its safe... It just depends on how close you are with them...
I Have been Raising chickens for about 11 years. But my rarest chicken yet was a Heshe chicken. Idk how rare it is to have one. But I had one 6 years back. Forgot the breed but the Heshe didn't lay eggs but looked like a hen and crowed like a roster but didn't do any roster behavior. I had It...
He was layed and hatched on my farm. I have A bunch of breeds at the time- Sovot Hanna,sexlink,silky,polish And some others. But I don't think I had a blue Andalusian hen or roster.
