ive got a cupple questions

1 my bp ate on sunday and has not pooped not even the white boney stuff and he has a hard lump about 2 scales up from his scale ive been letting him swim and that help in the past but usually it passes in about 3 to 4 days i feed once a week and tomarrow is feeding time again should i hold off or feed?

2 my bp (same one as above) has been active at night most of the time ive had him lately he hasnt been ive beraly seen him as hes always under his hide when i do handle him he is active tounge flicks and he responds to touch as he always had so should i be worried or is it just a normal thing to do at this time in the season( live in tx very warm and im not sure bout the sex of the snake)

3 ive noticed that my bp has skin that has been comming off now he just shed last mounth and it all came off i dont know if this is bad or not he has had about 100g wight increce in the last month could that be the reason (husbandry is good temps are 88 hot 79 cool humidity is in 55 to 60 and im useing cypress bed as substrate change the water every day)

4 anyone know a good way to break a cupple of unruly very defensive babies one male one female females most agressive
