My husband and I just hatched our first little flock of keets! 3 hatched on 8-6 and 1 on 8-7. Two of the later hatched keets are not standing up and walking. Their little legs are spread flat on the ground. I read that it can take over 24 hours for them to completely be able to stand up and walk? We have them in a bin for now with wood shavings. Is this ok to have as the floor? Any help or suggestions would be great! Thanks!
