Wow all the questions...
Welcome to BYC. Enjoy your time here..
2 weeks old and you still consider them darlings! You must have special guineas. At two weeks I would have mine on wood chips and nothing covering them. Like all birds, IMHO you need to have them on grit for a day or two before giving them something other than feed. I assume you are giving them game bird starter something around 27% protein.
A lot of the questions depend on where you live and what other birds and animals you have. I did not know they ate clover, mine seem to prefer eating bugs. But I seldom watch what they eat. I am too busy protecting life, limb and property from them to watch them eat.
I have never had keets that were not deathly afraid of us. No matter how much we try to be with them. They are always so flighty we find it best to leave ours alone as much as we can.
You are going to train them to go in every day/evening? Interesting, mine go in when they want, they stay out when they want. We use to try and force them in every night. It was a 2 hour event we normally lost. What they seem to like to do is have all the flock go into the coop except for one or two. Then while we spend our time chasing the lone wolf guinea around from roof top to roof top, to tree tops and then under something the others sneak out again. The ones that sneak out will quietly go sit on another roof and watch the excitement of the chase. I think they like to see if they can get me to swear at them. Normally they can.
I would never train mine to the sound of a bell, unless the bell was so heavy they could not carry it off and sell it for drugs and alcohol. I really want to hear how this goes. I am sure it can be done. Ours pick up on clues of things we do, if we set a lawn chair up in the areas we normally give out treats, they will come running. Unless they think we want them to come running. then they won't.
When we throw the kitchen scraps to the birds we just yell "Girls" and they all come running, but I am not sure they are not following the chickens and turkeys so maybe you can train them with the bell. I read all the nice things people say about their guineas, and to be honest, I do not recognize the behavior as guinea behavior.
I love my Guineas, but then I am sure Ted Bundy's Mother loved him too. Outlaw motorcycle gangs members are loved by someone normally. They serve a function, they entertain us with their antics. They keep the ticks at bay, they keep cabbage moths and worms out of my garden. We have box elder bugs by the billions if we do not have them around. They seldom if ever eat commercial feed for 7 months a year, so they are cheap to raise. They just forage for themselves.
They remind me if I have not opened the coop door early enough, (on the days they go in). They force my roosters to be better behaved. They have no remorse about teaching a bird that violates bird etiquette to not do it again.
I had some eggs that were pipped yesterday, I have not looked at them in 20 hours, I am going to look shortly. I need to get my courage up before opening the hatcher and reaching into it. I have 5 fingers on each hand this morning, I am hoping to have the same 5 this afternoon. I also have turkey eggs in another drawer on the hatcher and I hate to open it too often during hatching time, So that is part of the reason I have not looked in, there is nothing I can do anyways. I will get them out either today or tomorrow. I like to raise them with other birds because they seem to be better behaved.
I wish I could have answered your questions better. Maybe some of the people that own the nicer suburban guineas will be able to help you.
