We put the wee bird in our newly built flight this afternoon, to let him build up some strength before being released. We didn't do it at the weekend as it was very heavy rain. Mike checked him at 4.00pm and he was fine, we checked again at 5.30 and he was dead. We are totally gutted and completely blame ourselves. We just feel like giving up, and we shouldn't be doing this anyway if things like this are going to happen- we're so upset.
