Yeah, I hear you. I have one boy that has been a late bloomer. There's still moments I question his sex and he's almost 6 months! But with these, they were not a color that I wanted to stick with. So all boys and girls had to go. The chicks I have growing out now will be my new foundation. So, you're saying to give them all a chance and let them develop before picking which boys stay. That makes a lot of sense!
If you know that your fertility is good, then I wouldn't even mention a refund on fertility, unless you were having issues in that department. A lot of fertile eggs can be non viable after shipping. And when I've cracked eggs that appeared to be "clear" after 7-10 days of incubation, the yolk has been scrambled and I couldn't check for the bullseye.
Sounds perfect! Lol. My grandfather breeds pigeons. And they mate for life, so one boy to one girl. He couldn't understand why I was having trouble placing the Roos until I explained it to him. Not a big market for roosters!
I completely understand the postal service is a major play in the actual viability of the egg. So if the eggs look scrambled when they arrive would you send more?? I know these are basic questions I just need them also for when I do my shipping!!
