i have 3 silkies and they have been in their coop and run for about 3 weeks now and i kept them in the coop for the first week then opened it up to the run. now the day i opened it up to the run they didnt come out at all just kindof looked out the door. so the next day i set them out side in the run the little rooster was ok but the other 2 were scared so i put them back in the coop with the door open. now the little roo will go in and out all day but the other 2 dont come out at all.i did try and place them out again and they did fine and were out all day but didnt go in on their own. the next day they came out on their own and were out all day again and again i had to put them back in at night. but since then they won't come out. the roo goes in and out all day but the other 2 stay in. my question is why would they do this and is this some thing that is normal for silkies?do they have trouble seeing so dont want to go up or down the ramp? the little roo doesn't have any trouble using the ramp. they are 13wks old.
