Well yeah moving house would be one of the more expensive and disruptive ways of doing it
Our girl got pretty fat on it just before we shifted (eggs) - we didnt intentionally breed them (hence my not being properly set up this time around).
Having done it the hard way, I would really recommend getting well set up first if you arent already - I was so unprepared and as a result my babies were disrupted far more than I believe they should have been even with culling anything that looked a bit " iffy" . Trying to keep them fed without an established daphnia colony meant having to purchase more on a regular basis and no doubt slower growth as well (although its my first lot so I have nothing to compare them to).
If I was deliberately breeding I would have ensured my girl was in peak condition first to reduce the risk of her getting sick/being vulnerable after the fact (I consider myself lucky there since she had not long before had a leg injury and had just regrown her leg) - made sure I had ample containers and filtration and a good stock of all the food needed at the various stages of growth.
I think I have actually been quite lucky not to have a major disaster on my hands ..... but I have also worked really hard to try and ensure that didnt happen.
Hindsight is a wonderful thing aye LOL.
Not suggesting that you havent sorted all that - just looking back at what I would have done differently.
