pigeons on the roof

I wouldnt recomend this method, never heared of it before, and why would you not want to put the ybs out when they are babies???? surely its madness keeping them in till eyes change and cant be healthy for them.
Last year my new loft was finished late and kept ybs in until they were very old then moved them to the new loft, anyway soon as they went out they took off the loft and I lost lots in fact about 20 were missing by the end of the week, soon as they can fly they will fly and usually keep going until they are lost, well thats my experience and opinion.

i always try get ybs out as soon as i can after weaning, sometimes the same day........all the are usually going to do is look out the doorway or walk out onto the platform in front of the loft, the sooner they see the surrounding area the better in my opinion.........
